Subject: RISC-V: Fix documentation of __builtin_riscv_pause
X-Git-Tag: basepoints/gcc-15~6608
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=cf64ab18e3f820376ff20c663c7c7bf1af290f02;p=thirdparty%2Fgcc.git

RISC-V: Fix documentation of __builtin_riscv_pause

This built-in does not imply the 'Xgnuzihintpausestate' extension.
It does not change architectural state (because all HINTs are prohibited
from doing that).

gcc/ChangeLog:

	* doc/extend.texi: Fix the description of __builtin_riscv_pause.
