------- Comment #5 from steven at gcc dot gnu dot org 2005-10-19 13:13 ------- That patch is yet another example of why we constantly keep having compile time problems. Just add more, and more, and more, and more. And act surprised when someone notices that gcc 4.1 is four times as slow as 2.95.3 for very little benefit on x86 at least.
Why a new pass over all insns, instead of e.g. teaching postreload cse or postreload gcse about this kind of thing? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17390
