Chris Lattner 30ebdc4311 remove the last uses of Config/alloca.h
llvm-svn: 79873
2009-08-23 22:57:38 +00:00
Chris Lattner c521f54198 Prune #includes from llvm/Linker.h and llvm/System/Path.h,
forcing them down into various .cpp files.

This change also:
1. Renames TimeValue::toString() and Path::toString() to ::str()
   for similarity with the STL.
2. Removes all stream insertion support for sys::Path, forcing
   clients to call .str().
3. Removes a use of Config/alloca.h from bugpoint, using smallvector
   instead.
4. Weans llvm-db off <iostream>

sys::Path really needs to be gutted, but I don't have the desire to
do it at this point.

Daniel Dunbar 8b6be17777 When exec() fails, return 127 instead of errno; the parent process has no way to
distinguish that the result is errno, so it can't use it to provide more
information about the error (it also exposes the numeric value of errno).

Dan Gohman 0c96daabad On "Unix", if Program::FindProgramByName is given a name containing
slashes, just go with it, regardless of whether it looks like it will
be executable. This follows the behavior of sh(1) more closely.

Reid Kleckner 4b3a356493 Re-committing r76828 with the JIT memory manager changes now that the build
bots like the BumpPtrAllocator changes.

Reid Kleckner 921673225c Reverting r76825 and r76828, since they caused clang runtime errors and some build failure involving memset.
llvm-svn: 76838
2009-07-23 01:40:54 +00:00
Reid Kleckner 1a722d9b73 Make the JIT code emitter properly retry and ask for more memory when it runs
out of memory, and also make the default memory manager allocate more memory
when it runs out.

Also, switch function stubs and global data over to using the BumpPtrAllocator.

This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB
of memory, and instead allocates in 512K slabs.  I suspect this size could go
lower, especially on embedded platforms, now that more slabs can be allocated.

Dan Gohman 970da81e8a glibc has two versions of strerror_r, a standards compliant one and a GNU
specific one. The GNU one is chosen when _GNU_SOURCE is defined. g++ always
defines _GNU_SOURCE on linux platforms because glibc's headers won't compile
in C++ mode without it. The GNU strerror_r doesn't always modify the buffer
which causes empty error messages on linux.

This patch changes MakeErrMsg to use the return value of strerror_r to get
the string instead of assuming the buffer will be modified, on GLIBC.

Patch by Benjamin Kramer!

Daniel Dunbar 3222b9be04 Make Unix.h:MakeErrMsg separate the prefix and errno string, so we get:
clang: error: unable to make temporary file: /etc/cc: can't make
  unique filename: Permission denied

instead of 

  clang: error: unable to make temporary file: /etc/cc: can't make
  unique filenamePermission denied

for example.

Also, audited the uses of MakeErrMsg to make the prefix strings
consistent (not end with newline/punctuation/space/": ").

Daniel Dunbar fb1a6eb69b Add llvm::sys::getHostTriple and remove
llvm::sys::getOS{Name,Version}.

Right now the implementation just derives from LLVM_HOSTTRIPLE (which
is wrong, but it doesn't look like we have a define for the target
triple). Ideally this routine would actually be able to compute the
triple for targets we care about.
