Chris Lattner 3bc741a0d2 recognize an unsigned add with overflow idiom into uadd. ... This resolves a README entry and technically resolves PR4916, but we still get poor code for the testcase in that PR because GVN isn't CSE'ing uadd with add, filed as PR8817. Previously we got: _test7: ## @test7 addq %rsi, %rdi cmpq %rdi, %rsi movl $42, %eax cmovaq %rsi, %rax ret Now we get: _test7: ## @test7 addq %rsi, %rdi movl $42, %eax cmovbq %rsi, %rax ret llvm-svn: 122182		2010-12-19 19:37:52 +00:00
