Fix fixup evaluation when deciding what to relocate with. The previous logic was to first try without relocations at all and failing that stop on the first defined symbol. That was inefficient and incorrect in the case part of the expression could be simplified and another part could not (see included test). We now stop the evaluation when we get to a variable whose value can change (i.e. is weak). llvm-svn: 233187 2015-03-25 14:16:53 +01:00			`// RUN: llvm-mc -filetype=obj -triple x86_64-pc-linux < %s \| llvm-readobj -r \| FileCheck %s`

Update tests to not be as dependent on section numbers. Many of these predate llvm-readobj. With elf-dump we had to match a relocation to symbol number and symbol number to symbol name or section number. llvm-svn: 235015 2015-04-15 17:59:37 +02:00			`// CHECK: Section {{.*}} .rela.text {`

Fix PR23025. There is something in link.exe that requires a relocation to use a global symbol. Not doing so breaks the chrome build on windows. This patch sets isWeak for that to work. To compensate, we then need to look past those symbols when not creating relocations. This patch includes an ELF test that matches GNU as behaviour. I am still reducing the chrome build issue and will add a test once that is done. llvm-svn: 233318 2015-03-26 22:11:00 +01:00
