* test-release.sh: Ignore LC_CTYPE in sed invocation on DarwinHans Wennborg2016-01-271-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Here, sed is used to prepare object files for comparison via cmp. On my Darwin 15.4.0 machine, LC_CTYPE is set to UTF-8 (by default, I believe). Under these circumstances, anything sed is made to read will be treated as UTF-8, prompting it to signal an error if it is not, like so: % sed s/a/b/ <(head -n1 /dev/random) >/dev/null; echo $? sed: RE error: illegal byte sequence 1 % To make sed work as expected, I need to set LC_CTYPE to C: % env LC_CTYPE=C sed s/a/b/ <(head -n1 /dev/random) >/dev/null; echo $? 0 % Without this change, sed will exit with an error for every single file that it compares between phase 2 and phase 3, thereby making it look as if the differences were far larger than they are.

* [llvm-tblgen] Stop emitting the intrinsic name matching codeReid Kleckner2016-01-261-60/+0
| | | | | | | | | The AMDGPU backend was the last user of the old StringMatcher recognition code. Move it over to the new lookupLLVMIntrinsicName funciton, which is now improved to handle all of the interesting edge cases exposed by AMDGPU intrinsic names. llvm-svn: 258875
* Remove autoconf supportChris Bieneman2016-01-2612-267/+0
| | | | | | | | | | | | | | | | Summary: This patch is provided in preparation for removing autoconf on 1/26. The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html "I felt a great disturbance in the [build system], as if millions of [makefiles] suddenly cried out in terror and were suddenly silenced.

* Sort intrinsics by LLVM intrinsic name, rather than tablegen def nameReid Kleckner2016-01-261-0/+4
| | | | | | | | | | | | Step one towards using a simple binary search to lookup intrinsic IDs instead of our crazy table generated switch+memcmp+startswith code that makes Function.cpp take about a minute to compile. See PR24785 and PR11951 for why we should do this. The X86 backend contains tables that need to be sorted on intrinsic ID, so reorder those. llvm-svn: 258757
* [TableGen] Fix sort order of asm operand classesOliver Stannard2016-01-251-20/+85
| | | | | | | | | | | | | | | | | | | | | | This is a fix for https://llvm.org/bugs/show_bug.cgi?id=22796. The previous implementation of ClassInfo::operator< allowed cycles of classes such that x < y < z < x, meaning that a list of them cannot be correctly sorted, and the sort order could differ with different standard libraries. The original implementation sorted classes by ValueName if they were otherwise equal. This isn't strictly necessary, but some backends seem to accidentally rely on it. If I reverse this comparison I get 8 test failures spread across the AArch64, Mips and X86 backends, so I have left it in until those backends can be fixed. There was one case in the X86 backend where the observable behaviour of the assembler is changed by this patch. This was because some of the memory asm operands were not marked as children of X86MemAsmOperand. Differential Revision: http://reviews.llvm.org/D16141 llvm-svn: 258677

| | | | | | | | | | | | | | | | | | | | | instead of using symlinks Summary: In the past I have run into several problems with the way `test-release.sh` creates all the subproject directories as siblings, and then uses symlinks to stitch them all together. In some scenarios this leads to clang not being able to find header files, etc. This patch changes the script so it directly exports into the correct target locations for each subproject.

* Fix undefined behavior in llvm's local changes to googletest.Nico Weber2016-01-192-1/+5
| | | | | | | | | r100895 landed an llvm-only change to add minix support to googletest. It did that by putting "defined()" in a macro, which has undefined behavior.

In principle we should run lit's testsuite before testing LLVM using lit so that any problems with lit get discovered before testing LLVM so we can bail out early. However this implementation (``check-all`` runs all tests together) seemed simpler and will still report failing lit tests. Note that the tests and the configured ``lit.site.cfg`` have to be copied into the build directory to avoid polluting the source tree. llvm-svn: 257221

| | | | | | | | | | | | | | r252440 to the Hexagon target. This restores the previous behavior of not including the mnemonic in the classes table for every target that starts instruction lines with the mnemonic. Not only did the table size increase by 1 entry, but the class enum increased in size which caused every class in the array to increase in size. It also grew the size of the function that parsers tokens into classes by a substantial amount. This adds a new HasMnemonicFirst flag to all AsmParsers. It's set to 1 by default and Hexagon target overrides it to 0. For the X86 target alone this recovers 324KB of size on the llvm-mc executable. I believe the current state is still a bad design choice for the Hexagon target as it causes most of the parsing to do a linear search through the entire match table to comparing operands against every instruction until it finds one that works. At least for the other targets we do a binary search based on mnemonic over which to do the linear scan. llvm-svn: 256669
