Changelog for nasm-2.16.03-lp154.78.1.x86_64.rpm :

* Thu Apr 18 2024 Michael Vetter - Update to 2.16.03:
* Fix building from git in a separate directory from the source.
* Remove some irrelevant files from the source distribution.
* Make the documentation stronger that -O0 or -O1 are probably not what the user wants. See section 2.1.24.
* Fix configure --enable-lto build option.
* Update the included RPM .spec file.
* Fri Apr 05 2024 Michael Vetter - Update to 2.16.02:
* Fix building from the source distribution in a separate directory from the source.
* Fix a number of issues when building from source, mostly involving configure or dependency generation. In particular, more aggressively avoid cross-compilation problems on Unix/Linux systems automatically invoking WINE. We could end up invoking WINE even when we didn\'t want to, making configure think it was running native when in fact cross-compiling.
* Hopefully fix compiling with the latest versions of MSVC/nmake.
* Windows host: add embedded manifest file. Without a manifest, Windows applications force a fixed PATH_MAX limit to any pathname; this is unnecessary.
* Add support VEX-encoded SM4-NI instructions.
* Add support for VEX-encoded SM3-NI instructions.
* Add support for VEX-encoded SHA512-NI instructions.
* PTWRITE opcode corrected (F3 prefix required.)
* Disassembler: the SMAP instructions are NP; notably the prefixed versions of CLAC are ERETU/ERETS.
* Add support for Flexible Return and Exception Delivery (FRED): the LKGS, ERETS and ERETU instructions.
* Fix external references to segments in the obj (OMF) and possibly other output formats.
* Always support up to 8 characters, i.e. 64 bits, in a string-to-numeric conversion.
* Preprocessor: add %map() function to expand a macro from a list of arguments, see section 4.4.7.
* Preprocessor: allow the user to specify the desired radix for an evaluated parameter. It doesn\'t make any direct difference, but can be nice for debugging or turning into strings. See the = modifier in section 4.2.1.
* Update documentation: __USE_package__ is now __?USE_package?__.
* Documentation: correct a minor problem in the expression grammar for Dx statements, see section 3.2.1.
* Preprocessor: correctly handle empty %rep blocks.
* Preprocessor: add options for a base prefix to %num(), see section 4.4.8.
* Preprocessor: add a %hex() function, equivalent to %eval() except that it producess hexadecimal values that are nevertheless valid NASM numeric constants, see section 4.4.5.
* Preprocessor: fix the parameter number in error messages (should be 1-based, like %num references to multi-line macro arguments.)
* Documentation: be more clear than the bin format is simply a linker built into NASM. See section 8.1.
* Adjust the LOCK prefix warning for XCHG. LOCK XCHG reg,mem would issue a warning for being unlockable, which is incorrect. In this case the reg,mem encoding is simply an alias for the mem,reg encoding. However, XCHG is always locked, so create a new warning (-w+prefix-lock-xchg) to explicitly flag a user-specified LOCK XCHG; default off. Future versions of NASM may remove the LOCK prefix when optimization is enabled.
* Fix broken dependency-list generation.
* Add optional warnings for specific relocation types (-w+reloc-
*, see appendix A), default off.
* Some target environments may have specific restrictions on what kinds of relocations are possible or allowed.
* Error out on certain bad syntax in Dx statements, such as db 1 2. See section 3.2.1.
* Thu Dec 22 2022 Michael Vetter - Update to 2.16.01:
* Fix the creation of the table of contents in the HTML version of the documentation.
* Wed Dec 21 2022 Michael Vetter - Update to 2.16:
* Support for the rdf format has been discontinued and all the RDOFF utilities has been removed.
* The --reproducible option now leaves the filename field in the COFF object format blank. This was always rather useless since it is only 18 characters long; as such debug formats have to carry their own filename information anyway.
* Fix handling of MASM-syntax reserved memory (e.g. dw ?) when used in structure definitions.
* The preprocessor now supports functions, which can be less verbose and more convenient than the equivalent code implemented using directives. See ppfunc.
* Fix the handling of %00 in the preprocessor.
* Fix incorrect handling of path names affecting error messages, dependency generation, and debug format output.
* Support for the RDOFF output format and the RDOFF tools have been removed. The RDOFF tools had already been broken since at least NASM 2.14. For flat code the ELF output format recommended; for segmented code the obj (OMF) output format.
* New facility: preprocessor functions. Preprocessor functions, which are expanded similarly to single-line macros, can greatly simplify code that in the past would have required a lengthy list of directives and intermediate macros. See ppfunc.
* Single-line macros can now declare parameters (using a && prefix) that creates a quoted string, but does not requote an already quoted string. See define.
* Instruction table updated per public information available as of November 2022.
* All warnings in the preprocessor have now been assigned warning classes. See warnings.
* Fix the invalid use of RELA-type relocations instead of REL-type relocations when generating DWARF debug information for the elf32 output format.
* Fix the handling at in istruc when the structure contains local labels. See istruc.
* When assembling with --reproducible, don\'t encode the filename in the COFF header for the coff}, win32 or win64 output formats. The COFF header only has space for an 18-character filename, which makes this field rather useless in the first place. Debug output data, if enabled, is not affected.
* Fix incorrect size calculation when using MASM syntax for non-byte reservations (e.g. dw ?.)
* Allow forcing an instruction in 64-bit mode to have a (possibly redundant) REX prefix, using the syntax rex as a prefix.
* Add a vex prefix to enforce VEX (AVX) encoding of an instruction, either using the 2- or 3-byte VEX prefixes.
* The CPU directive has been augmented to allow control of generation of VEX (AVX) versus EVEX (AVX-512) instruction formats, see CPU.
* Some recent instructions that previously have been only available using EVEX encodings are now also encodable using VEX (AVX) encodings. For backwards compatibility these encodings are not enabled by default, but can be generated either via an explicit vex prefix or by specifying either CPU LATEVEX or CPU NOEVEX; see CPU.
* Document the already existing unimacro directive. See unmacro.
* Fix a code range generation bug in the DWARF debug format (incorrect information in the DW_AT_high_pc field) for the ELF output formats. This bug happened to cancel out with a bug in older versions of the GNU binutils linker, but breaks with other linkers and updated or other linkers that expect the spec to be followed.
* Fix segment symbols with addends, e.g. jmp _TEXT+10h:0 in output formats that support segment relocations, e.g. the obj format.
* Fix various crashes and hangs on invalid input
* Fri Dec 16 2022 Dirk Müller - add reproducible.patch to avoid use of __DATE__
* Wed Oct 21 2020 Dominique Leuenberger - Update to version 2.15.05: + Fix {%ifid $} and {%ifid $$} incorrectly being treated as true. + Add {--reproducible} option to suppress NASM version numbers and timestamps in output files. See {opt-reproducible}.
* Mon Aug 24 2020 Dirk Mueller - update to 2.15.4:
* More sensible handling of the case where one single-line macro definition will shadow another.
* Add special preprocessor tokens \\c{%
*?} and \\c{%
*??} that expand like \\c{%?} and \\c{%??} in single-line macros only. See \\k{selfref%
*?}.
* Fix SSE instructions not being recognized with an explicit memory operation size (e.g. \\c{movsd qword [eax],xmm0}).
* The \\c{-L+} option no longer enables \\c{-Lw}, which is mainly useful to debug NASM crashes. See \\k{opt-L}.
* The NASM-only RDOFF output format backend, which has been broken since at least NASM 2.14, has been disabled. The RDOFF tools are scheduled to be removed from the NASM distribution in NASM 2.16. If you have a concrete use case for RDOFF, please file a NASM bug report at \\W{https://bugs.nasm.us/}\\c{https://bugs.nasm.us/} as soon as possible. See \\k{rdffmt}.
* Sat Jul 18 2020 Andreas Stieger - nasm 2.15.3:

* Support for bfloat16 floating-point constants
* various bug fixes
* Sat Jul 04 2020 Andreas Stieger - update to 2.15.2:
* Fix the handling of macro parameter ranges (%{:}), including with brace-enclosed original arguments- includes changes from 2.15.01:

* The comparison and booleanizing operators can now be used in any expression context, not just %if
* New operator ? ... :.
* Signed shift operators <<< and >>>
* The MASM DUP syntax for data definitions is now supported, in a somewhat enhanced form
* Warn for strange legacy behavior regarding empty arguments in multi-line macro expansion, but try to match legacy behavior in most cases. Legacy behavior can be disabled with the directive %pragma preproc sane_empty_expansion
* A much more sensible limit to expression evaluation depth. The previously defined limit would rarely trigger before NASM died with a stack overrun error on most systems
* The state of warnings can now be saved and restored via the [WARNING PUSH] and [WARNING POP] directives
* The sectalign on|off switch does not affect an explicit directive
* Fixed \'mismatch in operand sizes\' error in the MOVDDUP, CMPXCHG8B and CMPXCHG16B instructions.
* Removed obsolete gnu-elf-extensions warning about 8- and 16-bit relocation generation

* Added limited functionality MASM compatibility package
* Add single-line macros aliases using %defalias or %idefalias. These behave like a kind of \"symbolic links\" for single-line macros
* Added support for stringify, nostrip, evaluating, and greedy single-line macro arguments
* Unused single-line macro arguments no longer need to have a specified name
* Added conditional comma operator %,
* Changed private namespace from __foo__ to __?foo?__, so a user namespace starting from underscore is now clean from symbols. For backwards compatibility, the previous names are defined as aliases
* Added support of ELF weak symbols and external references
* Changed the behavior of the EXTERN keyword and introduced REQUIRED keyword
* Added %ifusable and %ifusing directives
* Made various performance improvements and stability fixes in macro preprocessor engine

* Add support for the note, preinit_array, init_array, and fini_array sections type in ELF
* Handle more than 32,633 sections in ELF
* Sat Nov 30 2019 Dominique Leuenberger - Convert changes file to proper UTF-8 format: new version of RPM are getting strict in interpreting files.

* Fix crash due to multiple errors or warnings during the code generation pass if a list file is specified.
* Create all system-defined macros defore processing command-line given preprocessing directives (-p, -d, -u, --pragma, --before).
* If debugging is enabled, define a __DEBUG_FORMAT__ predefined macro. See section 4.11.7.
* Fix an assert for the case in the obj format when a SEG operator refers to an EXTERN symbol declared further down in the code.
* Fix a corner case in the floating-point code where a binary, octal or hexadecimal floating-point having at least 32, 11, or 8 mantissa digits could produce slightly incorrect results under very specific conditions.
* Support -MD without a filename, for gcc compatibility. -MF can be used to set the dependencies output filename. See section 2.1.7.
* Fix -E in combination with -MD. See section 2.1.21.
* Fix missing errors on redefined labels; would cause convergence failure instead which is very slow and not easy to debug.
* Duplicate definitions of the same label with the same value is now explicitly permitted (2.14 would allow it in some circumstances.)
* Add the option --no-line to ignore %line directives in the source. See section 2.1.33 and section 4.10.1.
* Changed -I option semantics by adding a trailing path separator unconditionally.
* Fixed null dereference in corrupted invalid single line macros.

* Added the --pragma command line option to inject a %pragma directive. See section 2.1.29.
* Added the --before command line option to accept preprocess statement before input. See section 2.1.30.
* Added AVX512 VBMI2 (Additional Bit Manipulation), VNNI (Vector Neural Network), BITALG (Bit Algorithm), and GFNI (Galois Field New Instruction) instructions.
* Added the STATIC directive for local symbols that should be renamed using global-symbol rules. See section 6.8.
* Allow a symbol to be defined as EXTERN and then later overridden as GLOBAL or COMMON. Furthermore, a symbol declared EXTERN and then defined will be treated as GLOBAL. See section 6.5.
* The GLOBAL directive no longer is required to precede the definition of the symbol.
* Support private_extern as macho specific extension to the GLOBAL directive. See section 7.8.5.
