Lu <h...@gcc.gnu.org>: https://gcc.gnu.org/g:1a2b60b581c373e4ebcee9ee37c0ab2866f98950 commit r10-6090-g1a2b60b581c373e4ebcee9ee37c0ab2866f98950 Author: H.J. Lu <hjl.to...@gmail.com> Date: Mon Jan 20 05:02:14 2020 -0800 x32: Add x32 support to -mtls-dialect=gnu2 To add x32 support to -mtls-dialect=gnu2, we need to replace DI with P in GNU2 TLS patterns. Since DEST set by tls_dynamic_gnu2_64 is in ptr_mode, PLUS in GNU2 TLS address computation must be done in ptr_mode to support -maddress-mode=long. Also replace the "{q}" suffix on lea with "%z0" to support both 32-bit and 64-bit destination register. Tested on Linux/x86-64. gcc/ PR target/93319 * config/i386/i386.c (legitimize_tls_address): Pass Pmode to gen_tls_dynamic_gnu2_64.
