* Make llc use getHostCPUFeatures when 'native' is specified for cpu.Craig Topper2015-03-311-2/+3
| | | | | | This is necessary for x86 where not all Sandybridge, Ivybrige, Haswell, and Broadwell CPUs support AVX. Currently we modify the CPU name back to Nehalem for this case, but that turns off additional features for these CPUs. llvm-svn: 233673
* Convert feature strings to lowercase even if they have a '+'/'-' in front of ↵Craig Topper2015-03-281-1/+1

* Revert "Use std::bitset for SubtargetFeatures"Michael Kuperstein2015-03-241-12/+11
| | | | | | | | This reverts commit r233055. It still causes buildbot failures (gcc running out of memory on several platforms, and a self-host failure on arm), although less than the previous time. llvm-svn: 233068
* Use std::bitset for SubtargetFeaturesMichael Kuperstein2015-03-241-11/+12
| | | | | | | | | | | | | Previously, subtarget features were a bitfield with the underlying type being uint64_t. Since several targets (X86 and ARM, in particular) have hit or were very close to hitting this bound, switching the features to use a bitset. No functional change. The first time this was committed (r229831), it caused several buildbot failures. At least some of the ARM ones were due to gcc/binutils issues, and should now be fixed.

* Fix some cases where StringRef was being passed by const reference. Remove ↵Craig Topper2014-08-301-8/+8
| | | | | | const from some other StringRefs since its implicitly const already. llvm-svn: 216820
* SubTargetFeature.cpp: it seems the size of this SmallVector should be 3Hans Wennborg2014-08-111-1/+1

* ArrayRef-ize the Feature and Processor tables for SubtargetFeatures.Eric Christopher2014-05-061-60/+46
| | | | | | | | This removes arguments passed everywhere and allows the use of standard iteration over lists. Should be no functional change. llvm-svn: 208127
* Have the SubtargetFeature help routine just not return a number andEric Christopher2014-05-061-6/+4
| | | | | | | | fall back to the normal path without a cpu. While doing this fix llc to just exit when we don't have a module to process instead of asserting. llvm-svn: 208102
* Revert "Walk back commits for unused function parameters - they're still being"Eric Christopher2014-05-061-19/+5

* MC: Don't assume incoming StringRef's are null terminated.Will Dietz2013-10-131-4/+1
| | | | | | | | | | This can happen when processing command line arguments, which are often stored as std::string's and later turned into StringRef's via std::string::data(). Unfortunately this is not guaranteed to return a null-terminated string until C++11, causing breakage on platforms that don't do this. llvm-svn: 192558

* Change createAsmParser to take a MCSubtargetInfo instead of triple,Evan Cheng2011-07-091-0/+32
| | | | | | | | | CPU, and feature string. Parsing some asm directives can change subtarget state (e.g. .code 16) and it must be reflected in other modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance must be shared. llvm-svn: 134795

* Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name toEvan Cheng2011-06-301-41/+21
| | | | | | | | | | be the first encoded as the first feature. It then uses the CPU name to look up features / scheduling itineray even though clients know full well the CPU name being used to query these properties. The fix is to just have the clients explictly pass the CPU name! llvm-svn: 134127
