Eric Christopher	cee313d288	Revert "Temporarily Revert "Add basic loop fusion pass."" ... The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. llvm-svn: 358552	2019-04-17 04:52:47 +00:00
Eric Christopher	a863435128	Temporarily Revert "Add basic loop fusion pass." ... As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546	2019-04-17 02:12:23 +00:00
Dmitri Gribenko	b137c9e551	Tests: rewrite 'opt ... %s' to 'opt ... < %s' so that opt does not emit a ModuleID ... This is done to avoid odd test failures, like the one fixed in r171243. llvm-svn: 171246	2012-12-30 01:28:40 +00:00
Rafael Espindola	751677a040	Don't merge two constants if we care about the address of both. ... This fixes the original testcase in PR8927. It also causes a clang binary built with a patched clang to increase in size by 0.21%. We can probably get some of the size back by writing a pass that detects that a global never has its pointer compared and adds unnamed_addr to it (maybe extend global opt). It is also possible that there are some other cases clang could add unnamed_addr to. I will investigate extending globalopt next. llvm-svn: 123584	2011-01-16 17:05:09 +00:00
Nick Lewycky	0296a481f9	Make constmerge a two-pass algorithm so that it won't miss merging ... opporuntities. Fixes PR8978. llvm-svn: 123541	2011-01-15 18:14:21 +00:00
