[ELF] Move `// REQUIRES:` line to the top llvm-svn: 335676
2018-06-27 06:20:04 +08:00
// REQUIRES: x86
Keep the largest common symbol. This requires templating some functions over ELFT, but that opens other cleanup opportunities for future patches. llvm-svn: 246405

Rename ld.lld2 to ld.lld since it is the default. llvm-svn: 253437

[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

[ELF][X86] Allow PT_LOAD to have overlapping p_offset ranges on EM_X86_64 Port the D64906 technique to EM_X86_64. Differential Revision: https://reviews.llvm.org/D67482 llvm-svn: 371958

// CHECK-NEXT: Offset:
Currently lld creates a single section to collect all commons. There is no way to separate commons based on file name patterns. The following linker script construct does not work because commons are allocated before section placement is done and the only synthesized BssSection that holds all commons has no file associated with it: SECTIONS { .common_0 : { *file0.o(COMMON) }} This patch changes the allocation of commons to create a section per common symbol and let the section logic do the layout.

Use a MapVector to output symbols in a deterministic order. We used to sort the symbols at the very end, but we need to know the order earlier so that we can create reference to them in the dynamic relocations. Thanks to Igor Kudrin for pointing out the problem. llvm-svn: 247911
