The cygwin package of nasm has been update to version 2.10.05. This
is the latest stable upstream version available from http://nasm.us/
The Netwide Assembler, NASM, is an 80x86 and x86-64 assembler designed
for portability and modularity.
The full upstream changelog since the last Cygwin package (2.08.02) is
long; below are excerpts for the two major upstream releases. The
full history is available at http://nasm.us/doc/nasmdocc.html
Version 2.10:
- When optimization is enabled, mov r64,imm now optimizes to the
shortest form possible between:
mov r32,imm32 ; 5 bytes
mov r64,imm32 ; 7 bytes
mov r64,imm64 ; 10 bytes
- Add support for the Intel AVX2 instruction set.
- Add support for Bit Manipulation Instructions 1 and 2.
- Add support for Intel Transactional Synchronization Extensions
(TSX).
- Add support for x32 ELF (32-bit ELF with the CPU in 64-bit mode.)
- Add support for bigendian UTF-16 and UTF-32.
Version 2.09:
- Fixed assignment the magnitude of %rep counter. It is limited to
62 bits now.
- Fixed NULL dereference if argument of %strlen resolves to
whitespace. For example if nonexistent macro parameter is used.
- %ifenv, %elifenv, %ifnenv, and %elifnenv directives introduced.
- Fixed NULL dereference if environment variable is missed.
- Updates of new AVX v7 Intel instructions.
- PUSH imm32 is now officially documented.
- Fix for encoding the LFS, LGS and LSS in 64-bit mode.
- Fixes for compatibility with OpenWatcom compiler and DOS 8.3 file
format limitation.
- Macros parameters range expansion introduced.
- Backward compatibility on expanging of local sigle macros restored.
- 8 bit relocations for elf and bin output formats are introduced.
- Short intersegment jumps are permitted now.
- An alignment more than 64 bytes are allowed for win32, win64
output formats.
- SECTALIGN directive introduced.
- nojmp option introduced in smartalign package.
- Short aliases win, elf and macho for output formats are
introduced. Each stands for win32, elf32 and macho32 accordingly.
- Faster handling of missing directives implemented.
- Various small improvements in documentation.
- No hang anymore if unable to open malloc.log file.
- The environments without vsnprintf function are able to build nasm
again.
- AMD LWP instructions updated.
- Tighten EA checks. We warn a user if there overflow in EA
addressing.
- Make -Ox the default optimization level. For the legacy behavior,
specify -O0 explicitly.
- Environment variables read with %! or tested with %ifenv can now
contain non-identifier characters if surrounded by quotes.
- Add a new standard macro package %use fp for floating-point
convenience macros.
