2004-06-16Fix a recent regression in Applications/sgefa that Alkis pointed out to me.Chris Lattner
The vector may actually be empty if the register that we are marking as recently used is not actually allocatable. This happens for physical registers that are not allocatable, like the ST(x) registers on X86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14195 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-14Quick hack to get this file compiling again on Mac OS X. The right thing to doBrian Gaeke
is write an autoconf macro that checks whether __isnan or isnan actually works **using the C++ compiler after #include <cmath>**, instead of doing it the easy way with AC_CHECK_FUNCS(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14171 91177308-0d34-0410-b5e6-96231b3b80d8

-release causes ENABLE_OPTIMIZED=1 to be added to the make line so that the test runs against optimized code. -pedantic causes the CompileOptimizeOpts variable to be overridden to add several additional warnings not picked up by -Wall.

2004-06-11By far, one of the most common uses of isnan is to make 'isunordered'Chris Lattner
comparisons. In an 'isunordered' predicate, which looks like this at the LLVM level: %a = call bool %llvm.isnan(double %X) %b = call bool %llvm.isnan(double %Y) %COM = or bool %a, %b We used to generate this code: fxch %ST(1) fucomip %ST(0), %ST(0) setp %AL fucomip %ST(0), %ST(0) setp %AH or %AL, %AH With this patch, we generate this code: fucomip %ST(0), %ST(1) fstp %ST(0) setp %AL Which should make alkis happy.
