nasm-2.16.02

[Bruce Dubbs]

New point version.

[Xi Ruoyao]

• 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 "f_map".

• 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 "define".

• Update documentation: __USE_package__ is now __?USE_package?__.

• Documentation: correct a minor problem in the expression grammar for D*x* statements, see "db".

• Preprocessor: correctly handle empty %rep blocks.

• Preprocessor: add options for a base prefix to %num(), see "f_num".

• Preprocessor: add a %hex() function, equivalent to %eval() except that it producess hexadecimal values that are nevertheless valid NASM numeric constants, see "f_hex".

• 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 "binfmt".

• 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 "warnings"), 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 "db".
