* MemoryBuffer now return an error_code and returns a OwningPtr<MemoryBuffer> ↵Michael J. Spencer2010-12-161-34/+38

* add a MemoryBuffer::getOpenFile method, which turns an openChris Lattner2010-11-231-0/+7
| | | | | | file descriptor into a MemoryBuffer (and closes the FD). llvm-svn: 120065
* Revert functionality doug added in r98575 that was neverChris Lattner2010-11-231-15/+11
| | | | | | documented and only used by some clang stuff I just removed. llvm-svn: 120002
* Rewrite MemoryBuffer::getSTDIN to use read(2) and a SmallVector buffer.Benjamin Kramer2010-06-251-15/+15
| | | | llvm-svn: 106856
* Bring back the empty vector workaround I removed in r106839. Looks like MSVC ↵Benjamin Kramer2010-06-251-1/+2

* Tweak MemoryBuffer to allocate the class itself, the name and possibly theBenjamin Kramer2010-06-251-70/+60
| | | | | | | | | | buffer in the same chunk of memory. 2 less mallocs for every uninitialized MemoryBuffer and 1 less malloc for every MemoryBuffer pointing to a memory range translate into 20% less mallocs on clang -cc1 -Eonly Cocoa_h.m. llvm-svn: 106839
* Add overloads for getFile and getFileOrSTDIN which take a const char *Dan Gohman2010-06-241-3/+17
| | | | | | | instead of a StringRef, avoiding the need to copy the string in the common case. llvm-svn: 106754
* Add an explicit keyword.Dan Gohman2010-06-221-1/+1
| | | | llvm-svn: 106538
* Add basic error checking to MemoryBuffer::getSTDIN.Dan Gohman2010-05-271-2/+7

* stringref-ize the MemoryBuffer::get apis. This requiresChris Lattner2010-04-051-11/+8
| | | | | | a co-committed clang patch. llvm-svn: 100485
* Remove accidental include and add a comment.Benjamin Kramer2010-04-011-2/+2
| | | | llvm-svn: 100107
* Various improvements to MemoryBuffer::getFile:Benjamin Kramer2010-04-011-17/+26
| | | | | | | | | | - 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. llvm-svn: 100106
* Extend MemoryBuffer::getFile() to take an optional "stat" structureDouglas Gregor2010-03-151-7/+10
| | | | | | | pointer. If given, the structure will be set with the stat information from the file actually read. llvm-svn: 98575
* Replace a temporary std::string with SmallString.Benjamin Kramer2010-02-261-1/+2
| | | | llvm-svn: 97259
* sizeof(char) is always 1.Chris Lattner2009-12-231-2/+2
| | | | llvm-svn: 92079
* return more useful error messages by using strerror to format errnoChris Lattner2009-12-011-3/+3
| | | | | | instead of returning an ambiguous reason. llvm-svn: 90275
* Fix MemoryBuffer::getSTDIN to *not* return null if stdin is empty, this is a ↵Daniel Dunbar2009-11-101-16/+14
| | | | | | | | lame API. Also, Stringrefify some more MemoryBuffer functions, and add two performance FIXMEs. llvm-svn: 86630
* A value is only assigned to errno if NumRead equals -1, so doDuncan Sands2009-11-041-1/+1
| | | | | | not reason based on errno if NumRead has a different value. llvm-svn: 86046
* Make this code more robust by not thinking we are making progressDuncan Sands2009-11-031-1/+1
| | | | | | if zero bytes were read. llvm-svn: 85922
* Tweak MemoryBuffer::getSTDIN so that it returns after the first EOF. Eli Friedman2009-05-181-3/+6
| | | | | | | It doesn't matter for piped input, but it's annoying when typing at the console. llvm-svn: 71998
* Switch from new[] + delete[] to malloc + free since llvm does not catch C++ ↵Evan Cheng2009-02-131-3/+3
| | | | | | exceptions. llvm-svn: 64448
* If new[] fails, return 0 rather then trying to dereference a null pointer.Evan Cheng2009-02-131-3/+12
| | | | llvm-svn: 64444
* Fix more -Wshorten-64-to-32 warnings.Evan Cheng2008-05-051-3/+3

* fcntl.h is pretty standard on unix (without the sys/)Gabor Greif2008-04-301-2/+1

* Fix compilation errors on MSVC. Patch by Argiris Kirtzidis!Bill Wendling2008-04-011-1/+2
| | | | llvm-svn: 49055
* Change the MemoryBuffer::getFile* methods to take just a pointer to theChris Lattner2008-04-011-13/+8
| | | | | | | | start of a filename, not a filename+length. All clients can produce a null terminated name, and the system api's require null terminated strings anyway. llvm-svn: 49041
* Reimplement MemoryBuffer::getFile with three enhancements:Chris Lattner2008-04-011-85/+64
| | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 49031
* Remove the MappedFile::charBase member, rename base -> getBase() andChris Lattner2008-04-011-3/+4
| | | | | | make getBase() return a const-correct pointer. llvm-svn: 49025
* Remove MappedFile support for mapping files for write and execChris Lattner2008-04-011-1/+1
| | | | | | | and shared. This complicates the design, is not used, and probably doesn't even work. llvm-svn: 49022
