--- Comment #15 from Sourceware Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by H.J. Lu <h...@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=d774bf9b3623239a1cfa729afcf048a15da657d3 commit d774bf9b3623239a1cfa729afcf048a15da657d3 Author: Cui, Lili <lili....@intel.com> Date: Thu Sep 19 14:38:16 2024 +0800 x86: Add tls check in gas Assembler shouldn't accept invalid TLS instructions, TLS relocations can only be used with specific instructions as specified in TLS psABI and linker issues an error when TLS relocations are used with wrong instructions or format. Since it is inconvenient for gcc to rely on linker to report errors, adding TLS check in the assembler stage so that gcc can know TLS errors earlier. gas/ChangeLog: PR gas/32022 * config.in: Regenerate. * config/tc-i386.c *(enum x86_tls_error_type): New. *(struct _i386_insn): Added has_gotrel to indicate whether TLS relocations need to be checked.
