* [LLD][ELF] - Update tests after r352366.George Rimar2019-01-281-1/+1
| | | | | | | r352366 "[llvm-objdump] - Print LMAs when dumping section headers." changed the format of llvm-objdump output. We have to update the LLD tests. llvm-svn: 352372
* [ELF] Make non-writable non-executable PROGBITS sections closer to .textFangrui Song2018-06-261-2/+4
| | | | | | | | | | | | This generalizes the old heuristic placing SHT_DYNSYM SHT_DYNSTR first in the readonly SHF_ALLOC segment. Reviewers: espindola Subscribers: emaste, arichardson, llvm-commits Differential Revision: https://reviews.llvm.org/D48406 llvm-svn: 335674
* [lld] Mitigate relocation overflow [part 1 of 2].Han Shen2018-05-151-1/+3
| | | | | | | | | | | This CL places .dynsym and .dynstr at the beginning of SHF_ALLOC sections. We do this to mitigate the possibility that huge .dynsym and .dynstr sections placed between ro-data and text sections cause relocation overflow.

* [ELF] - Revert of: r332038, r332054, r332060, r332061, r332062, r332063George Rimar2018-05-111-3/+1
| | | | | | | | | | | This reverts "Mitigate relocation overflow [part 1 of 2]." and the following commits which were trying to fix the bots. At the moment of r332082, bots are still failing and we need to find the reason of test case breakages first of all. http://lab.llvm.org:8011/builders/llvm-clang-lld-x86_64-scei-ps4-windows10pro-fast/builds/17042/steps/test/logs/stdio http://lab.llvm.org:8011/builders/llvm-clang-lld-x86_64-scei-ps4-ubuntu-fast/builds/29845/steps/test/logs/stdio llvm-svn: 332085
* Mitigate relocation overflow [part 1 of 2].Han Shen2018-05-101-1/+3
| | | | | | | | | | | | This CL is to mitigate R_X86_64_PC32 relocation overflow problems for huge binaries that has near 4G allocated sections. By examining those binaries, there're 2 issues contributes to the problem: 1). huge ".dynsym" and ".dynstr" stands in the way between .rodata and .text 2). _init_array_start/end are placed at 0 if no ".init_array" presents, this causes .text relocation against them become more prone to overflow. This CL addresses 1st problem (the 2nd will be addressed in another CL.) by assigning a smaller sortrank to .dynsym and .dynstr thus they no longer stand in between. llvm-svn: 332038
* Write some tests as linker scripts instead of assembly files.Rui Ueyama2018-02-281-0/+18
Some linker script test cases contain only a few lines of assembly and a long linker script. Such tests are easier to maintain if we write the main test file as a linkier script instead of assembly. Differential Revision: https://reviews.llvm.org/D43887 llvm-svn: 326363
