[LTO] Include in .symtab/.dynsym symbols introduced by optimizations. Some optimizations, e.g. SimplifyLibCalls, can replace functions with others as part of the lowering, e.g. printf => puts. The new symbols don't have the isUsedInRegularObj flag set so they don't get included in the final symbol table (and dynamic symbol table), and the dynamic linker gets confused. Include them as a fix. Differential Revision: http://reviews.llvm.org/D18357 llvm-svn: 264688

[ELF] Remove -m argument to lld in test files. NFC. This should be correctly implied by the linker. This also makes the tests slightly easier to maintain and compare with the equivalent tests under for other platforms. Differential Revision: https://reviews.llvm.org/D47513 llvm-svn: 333567

[test] Change llvm-readobj -long-option to --long-option or well-known short options. NFC Also change some options that have different semantics (cause confusion) in llvm-readelf mode: -s => -S -t => --symbols -sd => --section-data llvm-svn: 359651

Reland "Change the X86 datalayout to add three address spaces for 32 bit signed, 32 bit unsigned, and 64 bit pointers." This reverts 57076d3199fc2b0af4a3736b7749dd5462cacda5.

[ELF] Remove checking for spurious '@' at the end of dynamic sym names llvm-readobj currently has a bug (see PR40097) where it prints '@' at the end of unversioned dynamic symbols. This bug will be fixed in a separate later commit, but these tests need fixing first. Reviewed by: ruiu, Higuoxing Differential Revision: https://reviews.llvm.org/D56388 llvm-svn: 350614
