--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Iain D Sandoe <ia...@gcc.gnu.org>: https://gcc.gnu.org/g:5e39897ee2c73938fa940c4792d987608aeeebcd commit r14-8931-g5e39897ee2c73938fa940c4792d987608aeeebcd Author: Iain Sandoe <i...@sandoe.co.uk> Date: Sat Feb 10 14:44:41 2024 +0000 x86, libgcc: Implement ia32 basic heap trampoline [PR113855]. The initial heap trampoline implementation was targeting 64b platforms. As the PR demonstrates this creates an issue where it is expected that the same symbols are exported for 32 and 64b. Rather than conditionalize the exports and code-gen on x86_64, this patch provides a basic implementation of the IA32 trampoline. This also avoids potential user confusion, when a 32b target has 64b multilibs, and vice versa; which is the case for Darwin. PR target/113855 gcc/ChangeLog: * config/i386/darwin.h (DARWIN_HEAP_T_LIB): Moved to be available to all sub-targets. * config/i386/darwin32-biarch.h (DARWIN_HEAP_T_LIB): Delete. * config/i386/darwin64-biarch.h (DARWIN_HEAP_T_LIB): Delete. libgcc/ChangeLog: * config.host: Add trampoline support to x?86-linux. * config/i386/heap-trampoline.c (trampoline_insns): Provide a variant for IA32. (union ix86_trampoline): Likewise. (__gcc_nested_func_ptr_created): Implement a basic trampoline for IA32.
