From: Alexandre Oliva <aoliva@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc(refs/users/aoliva/heads/testme)] i386 testsuite: cope with --eable-default-pie Date: Mon, 11 Jul 2022 20:13:23 +0000 (GMT) [thread overview] Message-ID: <20220711201323.C764C3858023@sourceware.org> (raw) https://gcc.gnu.org/g:264d8826475b727d94c4c5974f3e1a4a8d28aba3 commit 264d8826475b727d94c4c5974f3e1a4a8d28aba3 Author: Alexandre Oliva <oliva@adacore.com> Date: Mon Jul 11 17:11:38 2022 -0300 i386 testsuite: cope with --eable-default-pie Running the testsuite on a toolchain build with --enable-default-pie had some unexpected fails. Adjust the tests to tolerate the effects of this configuration option on x86_64-linux-gnu and i686-linux-gnu. The cet-sjlj* tests get offsets before the base symbol name with PIC or PIE. A single pattern covering both alternatives somehow triggered two matches rather than the single expected match, thus my narrowing the '.*' to not skip line breaks, but that was not enough. Still puzzled, I separated the patterns into nonpic and !nonpic, and we get the expected matchcounts this way. Tests for -mfentry require an mfentry effective target, which excludes 32-bit x86 with PIC or PIE enabled, that's why the patterns that accept the PIC sym@RELOC annotations only cover x86_64. The pr24414 test stores in an unadorned named variable in an old-style asm statement, to check that such asm statements get an implicit memory clobber. Rewriting the asm into a GCC extended asm with the variable as an output would remove the regression it checks against. Problem is, the literal reference to the variable is not PIC, so it's rejected by the elf64 linker with an error, and flagged with a warning by the elf32 one. We could presumably make the variable references PIC-friendly with #ifdefs, but I doubt that's worth the trouble. I'm just arranging for the test to be skipped if PIC or PIE are enabled by default. for gcc/testsuite/ChangeLog * gcc.target/i386/cet-sjlj-6a.c: Cope with --enable-default-pie. * gcc.target/i386/cet-sjlj-6b.c: Likewise. * gcc.target/i386/fentryname3.c: Likewise. * gcc.target/i386/pr24414.c: Likewise. * gcc.target/i386/pr93492-3.c: Likewise. * gcc.target/i386/pr93492-5.c: Likewise. * gcc.target/i386/pr98482-1.c: Likewise.
