2003-07-22Fixed the enable/disable options. The AC_ARG_ENABLE macro does not performJohn Criswell
the *action-if-not-given* code when the --disable option is used. Rather, the AC_ARG_ENABLE macro sets the $enableval variable, which then needs to be checked to determine if --enable, --disable, or neither was specified. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7238 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-18Please, save your applause^H^H^H^H^H^H^H^Hflames for the end...Brian Gaeke
Avoid a fall-through in the (stubby) treatment of the longjmp intrinsic call which causes llc & lli to core-dump. Add a sort-of treatment of cast double to ulong. I am not really sure what a user should expect to see upon casting a negative FP value to unsigned long long. But with what is given here, I was able to write a program that could cast -123.456 to ulong and back and get -123.0, which seems like a step in the right direction. GCC seems to give you 0. I don't know if I'd consider that useful. These cases were coming up in GNU coreutils-5.0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7205 91177308-0d34-0410-b5e6-96231b3b80d8
