Alexander Kornienko 8a99824c5a Revert r203962 and two revisions depending on it: r204028 and r204059. ... The revision I'm reverting breaks handling of transitive aliases. This blocks us and breaks sanitizer bootstrap: http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-bootstrap/builds/2651 (and checked locally by Alexey). This revision is the result of: svn merge -r204059:204058 -r204028:204027 -r203962:203961 . + the regression test added to test/MC/ELF/alias.s Another way to reproduce the regression with clang: $ cat q.c void a1(); void a2() __attribute__((alias("a1"))); void a3() __attribute__((alias("a2"))); void a1() {} $ ~/work/llvm-build/bin/clang-3.5-good -c q.c && mv q.o good.o && \ ~/work/llvm-build/bin/clang-3.5-bad -c q.c && mv q.o bad.o && \ objdump -t good.o bad.o good.o: file format elf64-x86-64 SYMBOL TABLE: 0000000000000000 l df *ABS* 0000000000000000 q.c 0000000000000000 l d .text 0000000000000000 .text 0000000000000000 l d .data 0000000000000000 .data 0000000000000000 l d .bss 0000000000000000 .bss 0000000000000000 l d .comment 0000000000000000 .comment 0000000000000000 l d .note.GNU-stack 0000000000000000 .note.GNU-stack 0000000000000000 l d .eh_frame 0000000000000000 .eh_frame 0000000000000000 g F .text 0000000000000006 a1 0000000000000000 g F .text 0000000000000006 a2 0000000000000000 g F .text 0000000000000006 a3 bad.o: file format elf64-x86-64 SYMBOL TABLE: 0000000000000000 l df *ABS* 0000000000000000 q.c 0000000000000000 l d .text 0000000000000000 .text 0000000000000000 l d .data 0000000000000000 .data 0000000000000000 l d .bss 0000000000000000 .bss 0000000000000000 l d .comment 0000000000000000 .comment 0000000000000000 l d .note.GNU-stack 0000000000000000 .note.GNU-stack 0000000000000000 l d .eh_frame 0000000000000000 .eh_frame 0000000000000000 g F .text 0000000000000006 a1 0000000000000000 g F .text 0000000000000006 a2 0000000000000000 g .text 0000000000000000 a3 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204137 91177308-0d34-0410-b5e6-96231b3b80d8		2014-03-18 10:36:11 +00:00
