* llvm-reduce: Add pass to reduce instructionsDavid Blaikie2019-09-191-4/+2
| | | | | | | | Patch by Diego Treviño! Differential Revision: https://reviews.llvm.org/D66263 llvm-svn: 372282

* Fix llvm-reduce tests so that they don't assume the source code isTim Shen2019-09-121-2/+1

* llvm-reduce: For now, mark these tests as requiring a shellDavid Blaikie2019-09-121-0/+1

* PR43278: llvm-reduce: Use temporary file names (and ToolOutputFile) rather ↵David Blaikie2019-09-121-2/+2
| | | | | | | | | | | | | | | than unique ones - to ensure they're cleaned up This modifies the tool somewhat to only create files when about to run the "interestingness" test, and delete them immediately after - this means some more files will be created sometimes (when "double checking" work - which should probably be fixed/avoided anyway). This now creates temporary files, rather than only unique ones, and also uses ToolOutputFile (without ever calling "keep") to ensure the files are deleted as soon as the interestingness test is run. llvm-svn: 371696
* PR43278: Temporarily disable llvm-reduce tests due to exhausting temp filesDavid Blaikie2019-09-111-2/+2

* [Bugpoint redesign] Added Pass to Remove Global VariablesDiego Trevino Ferrer2019-08-151-0/+29
| | | | | | | | | | | | | | | | | Summary: This pass tries to remove Global Variables, as well as their derived uses. For example if a variable `@x` is used by `%call1` and `%call2`, both these uses and the definition of `@x` are deleted. Moreover if `%call1` or `%call2` are used elsewhere those uses are also deleted, and so on recursively. I'm still uncertain if this pass should remove derived uses, I'm open to suggestions.

* Revert [Bugpoint redesign] Added Pass to Remove Global VariablesDiego Trevino Ferrer2019-08-151-30/+0
| | | | | | | | | | | | | | This reverts r368918 because it was unstable! It broke these builds: * http://lab.llvm.org:8011/builders/lld-x86_64-ubuntu-fast/builds/4649 * http://lab.llvm.org:8011/builders/clang-ppc64be-linux-lnt/builds/29966 * http://lab.llvm.org:8011/builders/clang-ppc64be-linux-lnt/builds/29964 But surprisingly this passed: * http://lab.llvm.org:8011/builders/clang-ppc64be-linux-lnt/builds/29965 llvm-svn: 369039
