--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Christophe Lyon <cl...@gcc.gnu.org>: https://gcc.gnu.org/g:e2285af309000b74da0f7dc756a0b55e5f0b1b56 commit r13-102-ge2285af309000b74da0f7dc756a0b55e5f0b1b56 Author: Christophe Lyon <christophe.l...@arm.com> Date: Tue Apr 19 17:34:04 2022 +0200 arm: Restrict support of vectors of boolean immediates (PR target/104662) This simple patch avoids the ICE described in the PR: internal compiler error: in simd_valid_immediate, at config/arm/arm.cc:12866 with an early exit from simd_valid_immediate if we are trying to handle a vector of booleans and MVE is not enabled. We still get an ICE when compiling the existing gcc.dg/rtl/arm/mve-vxbi.c without -march=armv8.1-m.main+mve: error: unrecognizable insn: (insn 7 5 8 2 (set (reg:V4BI 114) (const_vector:V4BI [ (const_int 1 [0x1]) (const_int 0 [0]) repeated x2 (const_int 1 [0x1]) ])) -1 (nil)) during RTL pass: ira but there's little we can do since the testcase explicitly creates vectors of booleans which do need MVE. That is the reason why I do not add a testcase. 2022-04-19 Christophe Lyon <christophe.l...@arm.com> PR target/104662 * config/arm/arm.cc (simd_valid_immediate): Exit when input is a vector of booleans and MVE is not enabled.
