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

2005-07-12In support of PR418:Reid Spencer
Make sure that -lpthread gets added to LIBS variable which puts it at the end of the tools' link commands, if libpthread.a is found. Add a test for pthread.h so we can use #ifdef HAVE_PTHREAD_H git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22401 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

2005-07-12Fix PR576.Chris Lattner
Instead of emitting a JIT stub that looks like this: internal void %l1_main_entry_2E_ce_wrapper(int) { header: %resolver = call sbyte* %getPointerToNamedFunction( sbyte* getelementptr ([20 x sbyte]* %l1_main_entry_2E_ce_name, int 0, int 0) ) ; <sbyte*> [#uses=1] %resolverCast = cast sbyte* %resolver to void (int)* ; <void (int)*> [#uses=1] call void %resolverCast( int %0 ) ret void } Emit one that looks like this: internal void %l1_main_entry_2E_ce_wrapper(int) { Entry: %fpcache = load void (int)** %l1_main_entry_2E_ce.fpcache ; <void (int)*> [#uses=2] %isNull = seteq void (int)* %fpcache, null ; <bool> [#uses=1] br bool %isNull, label %lookupfp, label %usecache usecache: ; preds = %lookupfp, %Entry %fp = phi void (int)* [ %resolverCast, %lookupfp ], [ %fpcache, %Entry ] ; <void (int)*> [#uses=1] call void %fp( int %0 ) ret void lookupfp: ; preds = %Entry %resolver = call sbyte* %getPointerToNamedFunction( sbyte* getelementptr ([20 x sbyte]* %l1_main_entry_2E_ce_name, int 0, int 0) ) ; <sbyte*> [#uses=1] %resolverCast = cast sbyte* %resolver to void (int)* ; <void (int)*> [#uses=2] store void (int)* %resolverCast, void (int)** %l1_main_entry_2E_ce.fpcache br label %usecache } This makes the JIT debugger *MUCH* faster on large programs, as getPointerToNamedFunction takes time linear with the size of the program, and before we would call it every time a function in the text module was called from the safe module (ouch!). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22387 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-11add code to emit the .text section to the section header.Chris Lattner
Add a *VERY INITIAL* machine code emitter class.

2005-07-10Change *EXTLOAD to use an VTSDNode operand instead of being an MVTSDNode.Chris Lattner
This is the last MVTSDNode. This allows us to eliminate a bunch of special case code for handling MVTSDNodes.

2005-07-10Introduce a new VTSDNode class with the ultimate goal of eliminating theChris Lattner

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.
