[lld] Add REQUIRES: x86 where needed to tests If building lld without x86 support, tests that require that support should be treated as unsupported, not errors. Tested using: 1. cmake '-DLLVM_TARGETS_TO_BUILD=AArch64;X86' make check-lld => Expected Passes : 1406 Unsupported Tests : 287 2. cmake '-DLLVM_TARGETS_TO_BUILD=AArch64' make check-lld => Expected Passes : 410 Unsupported Tests : 1283 Patch by Joel Jones Differential Revision: https://reviews.llvm.org/D47748 llvm-svn: 334095

COFF: When resolving _load_config_used, add it as a GC root. This fixes the cases where the symbol is defined in a comdat or by bitcode. Differential Revision: http://reviews.llvm.org/D11673 llvm-svn: 243735

[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

COFF: Layout sections in the same order as link.exe One place where this seems to matter is to make sure the .rsrc section comes after .text. The Win32 UpdateResource() function can change the contents of .rsrc. It will move the sections that come after, but if .text gets moved, the entry point header will not get updated and the executable breaks. This was found by a test in Chromium.

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

[COFF] Don't hard-code the load configuration size The load configuration directory is a structure whose size varies as the OS gains additional functionality. To account for this, the structure's layout begins with a size field; this allows loaders to know which fields are available. However, LLD hard-coded the sizes (112 bytes for 64-bit and 64 for 32-bit). This means that we might not inform the loader of all the pertinent fields or we might claim that there are more fields than are actually present. To correctly account for this, the size field must be loaded from the _load_config_used symbol. N.B. The COFF spec is either wrong or out of date, the load configuration directory is not correctly documented in the specification: it omits the size field. llvm-svn: 263543
