--- Comment #4 from hjl at gcc dot gnu.org <hjl at gcc dot gnu.org> --- Author: hjl Date: Thu May 21 21:58:57 2015 New Revision: 223505 URL: https://gcc.gnu.org/viewcvs?rev=223505&root=gcc&view=rev Log: Allow indirect branch via GOT slot for x32 X32 doesn't support indirect branch via 32-bit memory slot since indirect branch will load 64-bit address from 64-bit memory slot. Since x32 GOT slot is 64-bit, we should allow indirect branch via GOT slot for x32. gcc/ PR target/66232 * config/i386/constraints.md (Bg): New constraint for GOT memory operand. * config/i386/i386.md (*call_got_x32): New pattern. (*call_value_got_x32): Likewise. * config/i386/predicates.md (GOT_memory_operand): New predicate. gcc/testsuite/ PR target/66232 * gcc.target/i386/pr66232-1.c: New test. * gcc.target/i386/pr66232-2.c: Likewise. * gcc.target/i386/pr66232-3.c: Likewise. * gcc.target/i386/pr66232-4.c: Likewise. * gcc.target/i386/pr66232-5.c: Likewise.
