--- Comment #8 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by H.J. Lu <[email protected]>: https://gcc.gnu.org/g:af8dbc9ccf8209007e38a923c3c158e9e8f4396d commit r17-2768-gaf8dbc9ccf8209007e38a923c3c158e9e8f4396d Author: Reshma Roy <[email protected]> Date: Tue Jul 28 16:55:24 2026 +0530 x86_cse: Check if DRAP is live with DF_LR_IN. The DRAP register has no reaching definition on function entry, so it never shows up in DF_LIVE_IN. When collecting the live caller-saved registers, additionally set DRAP's bit whenever it is live-in per DF_LR_IN, so the hoisted TLS call is kept after the DRAP save. PR target/126382 gcc/ChangeLog: * config/i386/i386-features.cc (ix86_emit_tls_call): Additional check to see if DRAP register is live in basic block with DF_LR_IN. gcc/testsuite/ChangeLog: * gcc.target/i386/pr126382.c: New test.
