* Revert "Reland [ELF] Loose a condition for relocation with a symbol"Vlad Tsyrklevich2019-07-221-2/+8
| | | | | | | This reverts commit r366686 as it appears to be causing buildbot failures on sanitizer-x86_64-linux-android and sanitizer-x86_64-linux. llvm-svn: 366708
* Reland [ELF] Loose a condition for relocation with a symbolNikola Prica2019-07-221-8/+2
| | | | | | | | | | | | | | | | | | | This patch was not the reason of the buildbot failure. Deleted code was introduced as a work around for a bug in the gold linker (http://sourceware.org/PR16794). Test case that was given as a reason for this part of code, the one on previous link, now works for the gold. This condition is too strict and when a code is compiled with debug info it forces generation of numerous relocations with symbol for architectures that do not have relocation addend.

* [llvm-readobj] Change -t to --symbols in tests. NFCFangrui Song2019-05-011-1/+1
| | | | | | | | | | -t is --symbols in llvm-readobj but --section-details (unimplemented) in readelf. The confusing option should not be used since we aim for improving compatibility. Keep just one llvm-readobj -t use case in test/tools/llvm-readobj/symbols.test llvm-svn: 359661
* [CodeGen] Unify MBB reference format in both MIR and debug outputFrancis Visoiu Mistrih2017-12-041-1/+1
| | | | | | | | | | | | | | | | As part of the unification of the debug format and the MIR format, print MBB references as '%bb.5'. The MIR printer prints the IR name of a MBB only for block definitions. * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#" << ([a-zA-Z0-9_]+)->getNumber\(\)/" << printMBBReference(*\1)/g' * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#" << ([a-zA-Z0-9_]+)\.getNumber\(\)/" << printMBBReference(\1)/g' * find . \( -name "*.txt" -o -name "*.s" -o -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#([0-9]+)/%bb.\1/g' * grep -nr 'BB#' and fix Differential Revision: https://reviews.llvm.org/D40422 llvm-svn: 319665
* Revert r240302 ("Bring r240130 back.").Daniel Jasper2015-06-231-4/+4
| | | | | | | | | | | | | This causes errors like: ld: error: blah.o: requires dynamic R_X86_64_PC32 reloc against '' which may overflow at runtime; recompile with -fPIC blah.cc:function f(): error: undefined reference to '' blah.o:g(): error: undefined reference to '' I have not yet come up with an appropriate reproduction. llvm-svn: 240394
* Bring r240130 back.Rafael Espindola2015-06-221-4/+4
| | | | | | | | | | | | | | | | | | | | | | Now that pr23900 is fixed, we can bring it back with no changes. Original message: Make all temporary symbols unnamed. What this does is make all symbols that would otherwise start with a .L (or L on MachO) unnamed. Some of these symbols still show up in the symbol table, but we can just make them unnamed. In order to make sure we produce identical results when going thought assembly, all .L (not just the compiler produced ones), are now unnamed. Running llc on llvm-as.opt.bc, the peak memory usage goes from 208.24MB to 205.57MB. llvm-svn: 240302
