Subject: [PATCH] x86-64: Save APX registers in ld.so trampoline
Date: Sun, 11 Feb 2024 16:46:06 -0800 [thread overview]
Message-ID: <20240212004606.969653-1-hjl.tools@gmail.com> (raw)
Remove bound registers from STATE_SAVE_MASK and add APX registers to
STATE_SAVE_MASK so that APX registers are saved in ld.so trampoline.
This fixes BZ #31371.
