| | | | | | | | | | | | vector that represents the .o file at once, build up a vector for each section of the .o file. This is needed because the .o file writer needs to be able to switch between sections as it emits them (e.g. switch between the .text section and the .rel section when emitting code).

* Break the code for expanding UINT_TO_FP operations out into its ownChris Lattner2005-07-161-35/+116
| | | | | | | | | | | | | | | SelectionDAGLegalize::ExpandLegalUINT_TO_FP method. Add a new method, PromoteLegalUINT_TO_FP, which allows targets to request that UINT_TO_FP operations be promoted to a larger input type. This is useful for targets that have some UINT_TO_FP or SINT_TO_FP operations but not all of them (like X86). The same should be done with SINT_TO_FP, but this patch does not do that yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22447 91177308-0d34-0410-b5e6-96231b3b80d8

* For PR540:Reid Spencer2005-07-1211-221/+155
| | | | | | | | | | | | | | | | | | | | | | | This patch completes the changes for making lli thread-safe. Here's the list of changes: * The Support/ThreadSupport* files were removed and replaced with the MutexGuard.h file since all ThreadSupport* declared was a Mutex Guard. The implementation of MutexGuard.h is now based on sys::Mutex which hides its implementation and makes it unnecessary to have the -NoSupport.h and -PThreads.h versions of ThreadSupport. * All places in ExecutionEngine that previously referred to "Mutex" now refer to sys::Mutex * All places in ExecutionEngine that previously referred to "MutexLocker" now refer to MutexGuard (this is frivolous but I believe the technically correct name for such a class is "Guard" not a "Locker"). These changes passed all of llvm-test. All we need now are some test cases that actually use multiple threads. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22404 91177308-0d34-0410-b5e6-96231b3b80d8
