2003-12-10Fixed a comma error.John Criswell
Added the --disable-threads option to GCC configure (to avoid pthread errors when building code with LLVM). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10380 91177308-0d34-0410-b5e6-96231b3b80d8

2003-12-10Upon Chris's suggestion, moved the #ifdef's to the generated C code.John Criswell
This makes LLVM and the generated C code more portable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10377 91177308-0d34-0410-b5e6-96231b3b80d8

2003-12-10Fixed the CBE on Solaris/Sparc. We need to define the return value ofJohn Criswell
the write() system call because it returns 64 bits on Solaris 64 bit, and an implicit return value of int says it returns 32 bits. Admittedly, this is a bit of a hack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10375 91177308-0d34-0410-b5e6-96231b3b80d8

2003-12-10Make LICM itself a bit more efficient, and make the generated code more ↵Chris Lattner
efficient too: don't insert a store in every exit block, because a particular block may be exited to more than once by a loop git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10369 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-10Removed the pthread_once() function because it doesn't actually doJohn Criswell
what it's supposed to do. Just leave this library as a dummy library for now until we have time to port a real pthread library (or get glibc working). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10368 91177308-0d34-0410-b5e6-96231b3b80d8
