2005-07-12Remove some code that moved to the generic asm printer a long time ago.Nate Begeman

2005-07-12For PR540:Reid Spencer
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
2005-07-12For PR540:Reid Spencer
Add a Mutex class for thread synchronization in a platform-independent way. The current implementation only supports pthreads. Win32 use of Critical Sections will be added later. The design permits other threading models to be used if (and only if) pthreads is not available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22403 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-12Implement Subtarget supportNate Begeman
Implement the X86 Subtarget. This consolidates the checks for target triple, and setting options based on target triple into one place. This allows us to convert the asm printer and isel over from being littered with "forDarwin", "forCygwin", etc. into just having the appropriate flags for each subtarget feature controlling the code for that feature. This patch also implements indirect external and weak references in the X86 pattern isel, for darwin. Next up is to convert over the asm printers to use this new interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22389 91177308-0d34-0410-b5e6-96231b3b80d8

1. Use isValid() to check validity of the resulting path name in the eraseSuffix even though we can't think of a case where eraseSuffix could possibly cause an invalid path name. 2.

2005-07-08Final Changes For PR495:Reid Spencer
This chagne just renames some sys::Path methods to ensure they are not misused. The Path documentation now divides methods into two dimensions: Path/Disk and accessor/mutator. Path accessors and mutators only operate on the Path object itself without making any disk accesses. Disk accessors and mutators will also access or modify the file system. Because of the potentially destructive nature of disk mutators, it was decided that all such methods should end in the work "Disk" to ensure the user recognizes that the change will occur on the file system. This patch makes that change. The method name changes are: makeReadable -> makeReadableOnDisk makeWriteable -> makeWriteableOnDisk makeExecutable -> makeExecutableOnDisk setStatusInfo -> setStatusInfoOnDisk createDirectory -> createDirectoryOnDisk createFile -> createFileOnDisk createTemporaryFile -> createTemporaryFileOnDisk destroy -> eraseFromDisk rename -> renamePathOnDisk These changes pass the Linux Deja Gnu tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22354 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-07For PR495:Reid Spencer
Get rid of the difference between file paths and directory paths. The Path class now simply stores a path that can refer to either a file or a directory. This required various changes in the implementation and interface of the class with the corresponding impact to its users. Doxygen comments were also updated to reflect these changes. Interface changes are: appendDirectory -> appendComponent appendFile -> appendComponent elideDirectory -> eraseComponent elideFile -> eraseComponent elideSuffix -> eraseSuffix renameFile -> rename setDirectory -> set setFile -> set Changes pass Dejagnu and llvm-test/SingleSource tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22349 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-06First round of support for doing scalar FP using the SSE2 ISA extension andNate Begeman
XMM registers. There are many known deficiencies and fixmes, which will be addressed ASAP. The major benefit of this work is that it will allow the LLVM register allocator to allocate FP registers across basic blocks. The x86 backend will still default to x87 style FP. To enable this work, you must pass -enable-sse-scalar-fp and either -sse2 or -sse3 to llc. An example before and after would be for: double foo(double *P) { double Sum = 0; int i; for (i = 0; i < 1000; ++i) Sum += P[i]; return Sum; } The inner loop looks like the following: x87: .LBB_foo_1: # no_exit fldl (%esp) faddl (%eax,%ecx,8) fstpl (%esp) incl %ecx cmpl $1000, %ecx #FP_REG_KILL jne .LBB_foo_1 # no_exit SSE2: addsd (%eax,%ecx,8), %xmm0 incl %ecx cmpl $1000, %ecx #FP_REG_KILL jne .LBB_foo_1 # no_exit git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22340 91177308-0d34-0410-b5e6-96231b3b80d8
