2008-04-01MappedFile is dead, remove it.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49035 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-01Implement Path::MapInFilePages/UnMapFilePages on unix, which Chris Lattner
provides fast MappedFile::getFile for large files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49034 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-01Reimplement MemoryBuffer::getFile with three enhancements:Chris Lattner
1) stop using MappedFile. 2) if profitable use the sys::path::MapInFilePages api to read the file. 3) otherwise fallback to read. When sys::path::MapInFilePages is implemented, this provides several benefits: #1: this avoids fragmenting memory for small files. #2: this avoids extraneous stat calls when the file size is known. #3: this only keeps the file descriptor open while reading the file, not for the duration of the lifetime of the memory buffer. This fixes a serious clang FD 'leak' problem. I believe that this will work on a win32 machine, but I don't have one to test on. I'd appreciate it if someone could check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49031 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-01change the archive stuff to use MemoryBuffer instead of mappedfile.Chris Lattner
MemoryBuffer is higher level and more closely matches the model needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49029 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-01Remove the MappedFile::charBase member, rename base -> getBase() andChris Lattner
make getBase() return a const-correct pointer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49025 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-01Change DiffFilesWithTolerance to be written in terms of MemoryBuffer,Chris Lattner
not an mmapped file. This more closely matches its requirements and provides an implicitly null terminated buffer, something this routine had to emulate itself before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49024 91177308-0d34-0410-b5e6-96231b3b80d8

and shared. This complicates the design, is not used, and probably doesn't even work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49022 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-01cleanup the MappedFile API and comments. This removes and updatesChris Lattner
tons of out of date comments (really nothing throws here!) and fixes some other fairly glaring issues: "size" used to return the size of the file *and* change it, depending on how you called it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49009 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-31Emit exception handling info for functions which areDale Johannesen
not marked nounwind, or for all functions when -enable-eh is set, provided the target supports Dwarf EH. llvm-gcc generates nounwind in the right places; other FEs will need to do so also. Given such a FE, -enable-eh should no longer be needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49006 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Mark functions in some tests as 'nounwind'. GeneratingDale Johannesen
EH info for these functions causes the tests to fail for random reasons (e.g. looking for 'or' or counting lines with asm-printer; labels count as lines.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49003 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-31The support for remat of instructions with a register operand is hackish, to ↵Evan Cheng
say the least. Since the register operand guaranteed to be PIC base and that it is already live at all uses, we are making sure it will not be spilled after its uses are rematerialized for both performance and correctness reasons. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48976 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Quote the ocaml executablesErick Tryzelaar
realazthat in #llvm was having problems building llvm because configure was finding an ocaml executable in a directory with a space in it's name.
