[Bug middle-end/93235] [AArch64] ICE with __fp16 in a struct
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93235 --- Comment #11 from CVS Commits --- The releases/gcc-8 branch has been updated by Jakub Jelinek : https://gcc.gnu.org/g:35936ba22c8e51c93c87e47114e194a84f9c9ba9 commit r8-10895-g35936ba22c8e51c93c87e47114e194a84f9c9ba9 Author: Jakub Jelinek Date: Thu Mar 4 19:38:08 2021 +0100 expand: Fix ICE in store_bit_field_using_insv [PR93235] The following testcase ICEs on aarch64. The problem is that op0 is (subreg:HI (reg:HF ...) 0) and because we can't create a SUBREG of a SUBREG and aarch64 doesn't have HImode insv, only SImode insv, store_bit_field_using_insv tries to create (subreg:SI (reg:HF ...) 0) which is not valid for the target and so gen_rtx_SUBREG ICEs. The following patch fixes it by punting if the to be created SUBREG doesn't validate, callers of store_bit_field_using_insv can handle the fallback. 2021-03-04 Jakub Jelinek PR middle-end/93235 * expmed.c (store_bit_field_using_insv): Return false of xop0 is a SUBREG and a SUBREG to op_mode can't be created. * gcc.target/aarch64/pr93235.c: New test. (cherry picked from commit 510ff5def87c70836fdbf832228661ae28e524b6)
