--- Comment #5 from cvs-commit at gcc dot gnu.org <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jose E. Marchesi <jema...@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=ff5a51b377212532a0cf2acea37c6a5672893d8f commit ff5a51b377212532a0cf2acea37c6a5672893d8f Author: Guillermo E. Martinez <guillermo.e.marti...@oracle.com> Date: Thu Apr 20 16:37:01 2023 +0200 gas: support for the BPF pseudo-c assembly syntax This patch adds support to the GNU assembler for an alternative assembly syntax used in BPF. This syntax is C-like and very unconventional for an assembly language, but it is generated by clang/llvm and is also used in inline asm templates in kernel code, so we ought to support it. After this patch, the assembler is able to parse instructions in both supported syntax: the normal assembly-like syntax and the pseudo-C syntax. Instruction formats can be mixed in the source program: the assembler recognizes the right syntax to use. gas/ChangeLog: 2023-04-20 Guillermo E.
