2010-06-08DeltaAlgorithm: Tweak split to split by first/second half instead of ↵Daniel Dunbar
even/odd, since adjacent changes are more likely to be related. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@105613 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-08ADT: Add DAGDeltaAlgorithm, which is a DAG minimization algorithm built on ↵Daniel Dunbar
top of the standard 'delta debugging' algorithm. - This can give substantial speedups in the delta process for inputs we can construct dependency information for. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@105612 91177308-0d34-0410-b5e6-96231b3b80d8

Evzen Muller! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103877 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-10Add new configure option, --disable-timestamps, intended to turn off ↵Daniel Dunbar
anything which would mess up binary/object comparisons. Currently: - Disables 'Built on ...' in 'foo --version'. - Disables timestamps from being embedded into .dir files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103423 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-08Run interrupt routines as part of report_fatal_error, since we are failingDaniel Dunbar
ungracefully. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103334 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-06Handle the case where open(2) or close(2) is interrupted by a signal whenDan Gohman
automatic syscall restarting is disabled. Also, fix the build on systems which don't define EWOULDBLOCK. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103158 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-06Handle EWOULDBLOCK as EAGAIN. And add a comment explaining whyDan Gohman
EAGAIN and EWOULDBLOCK are used here. Also, handle the case where a write call is interrupted after some data has already been written. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103153 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-05Implement rdar://7415680 - Twine integer support lacks greatnessChris Lattner
Microoptimize Twine's with unsigned and int to not pin their value to the stack. This saves stack space in common cases and allows mem2reg in the caller. A simple example is: void foo(const Twine &); void bar(int x) { foo("xyz: " + Twine(x)); } Before: __Z3bari: subq $40, %rsp movl %edi, 36(%rsp) leaq L_.str3(%rip), %rax leaq 36(%rsp), %rcx leaq 8(%rsp), %rdi movq %rax, 8(%rsp) movq %rcx, 16(%rsp) movb $3, 24(%rsp) movb $7, 25(%rsp) callq __Z3fooRKN4llvm5TwineE addq $40, %rsp ret After: __Z3bari: subq $24, %rsp leaq L_.str3(%rip), %rax movq %rax, (%rsp) movslq %edi, %rax movq %rax, 8(%rsp) movb $3, 16(%rsp) movb $7, 17(%rsp) leaq (%rsp), %rdi callq __Z3fooRKN4llvm5TwineE addq $24, %rsp ret It saves 16 bytes of stack and one instruction in this case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103107 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-05Try again if write(2) reports an recoverable error.Benjamin Kramer
This should fix mysteriously crashing boost regression tests when stderr is managed by bjam (PR7043). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103085 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13Let BumpPtrAllocator lazily allocate the first slab.Benjamin Kramer
We have some code in llvm and clang where a BumpPtrAllocator is declared in a class but never used in the common case. Stop wasting memory there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101130 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-06enhance SMDiagnostic to also maintain a pointer to the SourceMgr.Chris Lattner
Add a simplified constructor for clients that don't have locations like "file not found" errors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100538 91177308-0d34-0410-b5e6-96231b3b80d8

a co-committed clang patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100485 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-01Remove accidental include and add a comment.Benjamin Kramer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100107 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-01Various improvements to MemoryBuffer::getFile:Benjamin Kramer
- Use a RAII object to close the FD. - Use sys::StrError instead of thread-unsafe strerror calls. - Recover gracefully if read returns zero. This works around an issue on DragonFlyBSD where /dev/null has an st_size of 136 but we can't read 136 bytes from it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100106 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Introduce SpecificBumpPtrAllocator, a wrapper for BumpPtrAllocator which allowsBenjamin Kramer
only a single type of object to be allocated. Use it to make VNInfo destruction typesafe. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99919 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Introduce namespace-scope functions to enable LLVM statistics withoutDouglas Gregor
passing the command-line parameter "-stats" and to print the resulting statistics without calling llvm_shutdown(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99893 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-30Introduce another Reset() method in BumpPtrAllocator that calls a destructorTorok Edwin
on all objects it has allocated, if they are all of the same size and alignment. Use this to destruct all VNInfos allocated in LiveIntervalAnalysis (PR6653). valnos is not reliable for this purpose, as seen in r99400 (which still leaked, and sometimes caused double frees). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99881 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-30finally, maintain a global list of timer groups, allowing us to Chris Lattner

2010-03-30change TimerGroup to keep a linked list of active timers Chris Lattner
instead of just a count of them, and refactor the guts of report printing out of removeTimer into its own method. Refactor addTimerToPrint away. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99872 91177308-0d34-0410-b5e6-96231b3b80d8

timers by pointer instead of by-value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99871 91177308-0d34-0410-b5e6-96231b3b80d8
