This update for nasm fixes the following issues :

nasm was updated to version 2.14.02.

This allows building of Mozilla Firefox 78ESR and also contains lots of bugfixes, security fixes and improvements.

  - 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.

  - Fixed division by zero which may happen if source code     is malformed.

  - Fixed out of bound access in processing of malformed     segment override.

  - Fixed out of bound access in certain EQU parsing.

  - Fixed buffer underflow in float parsing.

  - Added SGX (Intel Software Guard Extensions)     instructions.

  - Added +n syntax for multiple contiguous registers.

  - Fixed subsections_via_symbols for macho object format.

  - Added the --gprefix, --gpostfix, --lprefix, and
    --lpostfix command line options, to allow command line     base symbol renaming. See section 2.1.28.

  - Allow label renaming to be specified by %pragma in     addition to from the command line. See section 6.9.

  - Supported generic %pragma namespaces, output and debug.
    See section 6.10.

  - 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.

  - Updated UD0 encoding to match with the specification

  - Added the --limit-X command line option to set execution     limits. See section 2.1.31.

  - Updated the Codeview version number to be aligned with     MASM.

  - Added the --keep-all command line option to preserve     output files. See section 2.1.32.

  - Added the --include command line option, an alias to -P     (section 2.1.18).

  - Added the --help command line option as an alias to -h     (section 3.1).

  - Added -W, -D, and -Q suffix aliases for RET instructions     so the operand sizes of these instructions can be     encoded without using o16, o32 or o64.

New upstream version 2.13.03 :

  - Add flags: AES, VAES, VPCLMULQDQ

  - Add VPCLMULQDQ instruction

  - elf: Add missing dwarf loc section

  - documentation updates This update was imported from the     SUSE:SLE-15:Update update project.

This update for nasm fixes the following issues :

nasm was updated to version 2.14.02.

This allows building of Mozilla Firefox 78ESR and also contains lots of bugfixes, security fixes and improvements.

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.

Fixed division by zero which may happen if source code is malformed.

Fixed out of bound access in processing of malformed segment override.

Fixed out of bound access in certain EQU parsing.

Fixed buffer underflow in float parsing.

Added SGX (Intel Software Guard Extensions) instructions.

Added +n syntax for multiple contiguous registers.

Fixed subsections_via_symbols for macho object format.

Added the --gprefix, --gpostfix, --lprefix, and --lpostfix command line options, to allow command line base symbol renaming. See section 2.1.28.

Allow label renaming to be specified by %pragma in addition to from the command line. See section 6.9.

Supported generic %pragma namespaces, output and debug. See section 6.10.

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.

Updated UD0 encoding to match with the specification

Added the --limit-X command line option to set execution limits. See section 2.1.31.

Updated the Codeview version number to be aligned with MASM.

Added the --keep-all command line option to preserve output files. See section 2.1.32.

Added the --include command line option, an alias to -P (section 2.1.18).

Added the --help command line option as an alias to -h (section 3.1).

Added -W, -D, and -Q suffix aliases for RET instructions so the operand sizes of these instructions can be encoded without using o16, o32 or o64.

New upstream version 2.13.03 :

Add flags: AES, VAES, VPCLMULQDQ

Add VPCLMULQDQ instruction

elf: Add missing dwarf loc section

It was discovered that NASM incorrectly handled certain source files.
If a user or automated system were tricked into processing a specially crafted source file, a remote attacker could use these issues to cause NASM to crash, resulting in a denial of service, or possibly execute arbitrary code.
