Duncan P. N. Exon Smith	ca06508c43	IR: Don't add inbounds to GEPs of extern_weak variables ... Global variables that have `extern_weak` linkage may be null, so it's incorrect to add `inbounds` when constant folding. This also fixes a bug when parsing global aliases, whose forward reference placeholders are global variables with `extern_weak` linkage. If GEPs to these aliases are encountered before the alias itself, the GEPs would incorrectly gain the `inbounds` keyword as well. llvm-svn: 215803	2014-08-16 01:54:32 +00:00
Duncan P. N. Exon Smith	d5508bfe28	verify-uselistorder: Change the default -num-shuffles=5 ... Change the default for `-num-shuffles` to 5 and better document the algorithm in the header docs of `verify-uselistorder`. llvm-svn: 214419	2014-07-31 18:46:24 +00:00
Duncan P. N. Exon Smith	f58c944271	verify-uselistorder: Add RUN lines to cases in test/Assembly ... Add RUN line for `verify-uselistorder` to every test in `test/Assembly`, unless it's a negative check (assembler rejects it) or verification fails. There are three files that verification fails on (so I've left out the RUN lines): - 2002-08-22-DominanceProblem.ll - ConstantExprFold.ll - ConstantExprFoldCast.ll This is part of PR5680. llvm-svn: 214365	2014-07-31 00:10:27 +00:00

Dan Gohman	e688173b6b	Fix ConstantFold's folding of icmp instructions to recognize that, ... for example, a one-past-the-end pointer from one global variable may be equal to the base pointer of another global variable. llvm-svn: 173995	2013-01-31 00:01:45 +00:00
