Chandler Carruth	ff123d5c63	Fix the remaining TCL-style quotes found in the testsuite. This is ... another mechanical change accomplished though the power of terrible Perl scripts. I have manually switched some "s to 's to make escaping simpler. While I started this to fix tests that aren't run in all configurations, the massive number of tests is due to a really frustrating fragility of our testing infrastructure: things like 'grep -v', 'not grep', and 'expected failures' can mask broken tests all too easily. Essentially, I'm deeply disturbed that I can change the testsuite so radically without causing any change in results for most platforms. =/ llvm-svn: 159547	2012-07-02 19:09:46 +00:00
Dan Gohman	40503396da	Eliminate more uses of llvm-as and llvm-dis. ... llvm-svn: 81290	2009-09-08 23:54:48 +00:00
Evan Cheng	7e9ef4d776	Now not UINT_TO_FP is legal (it's marked custom), dag combiner won't ... optimize it to a SINT_TO_FP when the sign bit is known zero. X86 isel should perform the optimization itself. llvm-svn: 62504	2009-01-19 08:08:22 +00:00
Chris Lattner	b1e66ce3bb	when we know the signbit of an input to uint_to_fp is zero, ... change it to sint_to_fp on targets where that is cheaper (and visaversa of course). This allows us to compile uint_to_fp to: _test: movl 4(%esp), %eax shrl $23, %eax cvtsi2ss %eax, %xmm0 movl 8(%esp), %eax movss %xmm0, (%eax) ret instead of: .align 3 LCPI1_0: ## double .long 0 ## double least significant word 4.5036e+15 .long 1127219200 ## double most significant word 4.5036e+15 .text .align 4,0x90 .globl _test _test: subl $12, %esp movl 16(%esp), %eax shrl $23, %eax movl %eax, (%esp) movl $1127219200, 4(%esp) movsd (%esp), %xmm0 subsd LCPI1_0, %xmm0 cvtsd2ss %xmm0, %xmm0 movl 20(%esp), %eax movss %xmm0, (%eax) addl $12, %esp ret llvm-svn: 52747	2008-06-26 00:16:49 +00:00
