2019-12-05llvm-reduce: Add a space to an option's --helpGeorge Burgess IV1-1/+1
Otherwise, we get "filewith".
2019-09-12PR43278: llvm-reduce: Use temporary file names (and ToolOutputFile) rather ↵David Blaikie1-4/+9
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
2019-09-10llvm-reduce: Simplify testing using -implicit-check-notDavid Blaikie1-2/+0
Also fix llvm-reduce to use the specified output file name directly, without appending '.ll' to the name. llvm-svn: 371555
2019-08-15[Bugpoint redesign] Output option can now print to STDOUTDiego Trevino Ferrer1-10/+15
Summary: This also changes all the outs() statements to errs() so the output and progress streams don't get mixed. This has been added because D64176 had flaky tests, which I believe were because the reduced file was being catted into `FileCheck`, instead of being pass from STDOUT directly.

This reverts commits: "Added Delta IR Reduction Tool" "[Bugpoint redesign] Added Pass to Remove Global Variables" "Added Tool as Dependency to tests & fixed warnings" Reduce/remove-funcs.ll is failing on bots. llvm-svn: 368122
2019-08-07[Bugpoint redesign] Added Pass to Remove Global VariablesDiego Trevino Ferrer1-2/+3
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.
