Reid Spencer 4ef4c46c35 For PR1302: 
Implement recognition of COFF, ELF and Mach-O object/shared lib files.

llvm-svn: 35650
 2007-04-04 06:30:26 +00:00
Reid Spencer c7f485fd71 Use the stat information in the Path object, if it is already obtained. This 
avoids a call to ::fstat by MappedFile when the file size information was
already obtained by the Path object.

 2007-03-29 19:11:22 +00:00
Reid Spencer 200c6f9c3d For PR789: 
Make the sys::Path::getFileStatus function more efficient by having it
return a pointer to the FileStatus structure rather than copy it. Adjust
uses of the function accordingly. Also, fix some memory issues in sys::Path.

Jeff Cohen 60c5522467 Determine absolute paths the correct way :) 
llvm-svn: 35464
 2007-03-29 17:27:38 +00:00
Reid Spencer d394617a55 Add a uniqueID field to the FileStatus structure for Paths. This will map 
to the inode number on Unix and something far less unique on Windows. The
windows case needs to be improved.

llvm-svn: 35461
 2007-03-29 17:00:31 +00:00
Reid Spencer 0f92f0e519 For PR789: 
* Add a method: bool isAbsolute() const, which determines if the path name
  is absolute or not.
* Implement caching of file status information in the Path object. Allow it
  to be updated forcefully or lazily re-fetched from the cached value.

Anton Korobeynikov d01defedf6 Add possibility to set memory limit for binaries run via libSystem. This 
is especially needed for bugpoint. This partly implements PR688

Reid Spencer a96084901c Help the lli interpreter find the stderr/stdin/stdout symbols. These are 
needed for output to be generated. On Linux these are both global vars and
macro definitions so we have to special case Linux.

llvm-svn: 33374
 2007-01-19 21:41:04 +00:00
Reid Spencer dcf6f90033 Handle each of stderr/stdin/stdout separately. 
llvm-svn: 33373
 2007-01-19 21:30:39 +00:00
Reid Spencer 750f80e306 Avoid taking the address of a macro by checking to see if stdin is defined 
or not. This allows DynamicLibrary.cpp to compile on Darwin.

llvm-svn: 33064
 2007-01-11 00:35:10 +00:00
Reid Spencer 1b2eeedd85 Allow LLI, in interpreter mode, to find stdin, stdout, and stderr. This is 
a bit of a hack but it lets some of the llvm-test programs run.

 2007-01-10 19:50:43 +00:00
Anton Korobeynikov eef04ba1c2 Partly fixed JITing on mingw32 platform. The support is not full due to 
absence of dllimport JIT codegen.

Chris Lattner 2f107cfc0d On Mac OS/X, make Process::PreventCoreFiles disable crash reporter for 
the process in addition to disabling core file emission.  This speeds up
bugpoint on default-configured macs by several orders of magnitude.

Chris Lattner 9543866c27 Guess what happens when asserts are disabled. :( 
Also, the assert could never fire due to || instead of &&.

Reid Spencer 50eac3b8ab For PR797: 
Make the Win32 code exception free (untested/uncompiled) which forced some
interface changes which had ripple effect. This should be the last of 797.

llvm-svn: 29884
 2006-08-25 21:37:17 +00:00
Reid Spencer 51e6f68b47 For PR797: 
Final commit for this bug. This removes the last EH holdouts in LLVM
and turns off exception support by using the -fno-exceptions option. This
leads to the following reduction in library and executable sizes:

Reid Spencer b5d6b8f26d For PR797: 
Adjust implementation to match the new interface after exception handling
was removed in the Unix verison. NOTE: this hasn't been compiled yet!

llvm-svn: 29858
 2006-08-24 18:58:37 +00:00
Reid Spencer dd27929918 Turn off exception handling for this library. It no longer throws nor 
handles exceptions.

llvm-svn: 29847
 2006-08-23 20:35:51 +00:00
Reid Spencer e4ca722199 For PR797:

 2006-08-22 22:46:39 +00:00
Reid Spencer 6ba87bbfd3 Make the sys::Path::GetTemporaryDirectory method not throw exceptions and 
adjust users of it to compensate.

llvm-svn: 29831
 2006-08-22 19:01:30 +00:00
Reid Spencer b1f9935407 Don't throw needlessly. Failure of gettimeofday is *very* unlinkely so 
just return MinTime if that should ever happen.

llvm-svn: 29826

Fix a bug in my last patch that botched file redirection by using explicit
scoping of if statements.

with an ErrMsg string argument.

llvm-svn: 29790
 2006-08-21 06:02:44 +00:00
Reid Spencer c295914b7a For PR797: 
Make sys::Program::ExecuteAndWait not throw exceptions and update any
affected code. It now return -9999 to signal that the program couldn't be
executed. Only one case (in bugpoint) actually examines the result code.

llvm-svn: 29785

Reid Spencer d6f8b1c70a Remove extraneous #include. 
llvm-svn: 29541
 2006-08-07 05:36:24 +00:00
Reid Spencer 448e2460e0 Make the removal of files use Path::eraseFromDisk just like it does for 
the removal of directories. Using std::remove is indiscriminate and can
lead to the removal of things like /dev/null if run as root. The
Path::eraseFromDisk method ensures that we only ever remove regular files
or directories, but never character or block special nodes.  This should
clear up the problem with usage like: llvm-as -o /dev/null which is used
in the llvm-test makefiles.
