* Several changes together in a murky mess:Chris Lattner2009-09-201-84/+102
| | | | | | | | | | | | 1. Change some "\n" -> '\n'. 2. eliminte some std::string's by using raw_ostream::indent. 3. move a bunch of code out of the main arg parser routine into a new static HandlePrefixedOrGroupedOption function. 4. Greatly simplify the implementation of getOptionPred, and make it avoid splitting prefix options at = when that doesn't match a non-prefix option. llvm-svn: 82362
* Fix refacto, this code was expecting to stride past the argument prefix.Daniel Dunbar2009-09-201-0/+1

* convert a bunch more stuff to use StringRef. The ArgName arguments are nowChris Lattner2009-09-201-28/+29

* Try to speed up the slowest parts of the CommandLine libraryBenjamin Kramer2009-09-191-28/+28
| | | | | | | | - Replace std::map<std::string with StringMap - Eliminate unnecessary std::string copies - ~10% speed-up for clang's testsuite on my machine (debug build) llvm-svn: 82312

* Drop the raw_ostream required buffer size to 1.Daniel Dunbar2009-09-151-2/+2
| | | | | | | - As best I can tell, we have eliminated all the code which used to require a larger buffer size. llvm-svn: 81912
* Update CMake files.Ted Kremenek2009-09-111-0/+1
| | | | llvm-svn: 81577
* Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn'tDan Gohman2009-09-112-2/+5
| | | | | | | | | | | | | | | working. To support this, add an is_displayed() function to raw_ostream, and generalize Process::StandardOutIsDisplayed and friends in order to support it. Also, call RemoveFileOnSignal before creating a file instead of after, so that the file isn't left behind if the program is interrupted between when the file is created and RemoveFileOnSignal is called. While here, add a -S to llvm-extract and port it to IRReader so that it supports assembly input. llvm-svn: 81568
* canonicalize namespace gymnasticsChris Lattner2009-09-091-23/+20

* Add comment re: clang dependency.Daniel Dunbar2009-09-091-0/+3

* Added an abstract superclass, MCDisassembler, forSean Callanan2009-09-091-0/+37
| | | | | | | | | | | | | all disassemblers. Modified the MemoryObject to support 64-bit address spaces, regardless of the LLVM process's address width. Modified the Target class to allow extraction of a MCDisassembler. llvm-svn: 81392
* Make sure the memory range is writable before memset'ing it.Evan Cheng2009-09-091-0/+2

* Remove some not-really-used variables, as warnedDuncan Sands2009-09-061-6/+9

* More MSVC warning fixes:Benjamin Kramer2009-09-063-2/+5
| | | | | | | 1. DUPMAX is defined in regcomp.c, no need to redefine it in regutils. 2. MSVC doesn't like snprintf, use _snprintf instead. llvm-svn: 81114
* Remove splint hints to silence warnings from ICC and MSVC.Benjamin Kramer2009-09-061-2/+2

* Make LLVM command-line tools overwrite their output files without -f.Dan Gohman2009-08-251-6/+6
| | | | | | | | | | | | | | | | This is conventional command-line tool behavior. -f now just means "enable binary output on terminals". Add a -f option to llvm-extract and llvm-link, for consistency. Remove F_Force from raw_fd_ostream and enable overwriting and truncating by default. Introduce an F_Excl flag to permit users to enable a failure when the file already exists. This flag is currently unused. Update Makefiles and documentation accordingly. llvm-svn: 79990
* CMake: updated list of source files.Oscar Fuentes2009-08-251-0/+1

* raw_ostream::indent is used for PadToColumn which often prints moreDan Gohman2009-08-241-3/+6

* split raw_os_ostream out to its own header and implementation file. ThisChris Lattner2009-08-242-14/+30
| | | | | | | means that raw_ostream no longer has to #include <iosfwd>. Nothing in llvm should use raw_os_ostream.h, but llvm-gcc and some unit tests do. llvm-svn: 79886
* prune the #includes in raw_ostream.h by moving a Chris Lattner2009-08-241-0/+8
| | | | | | | member out of line. ftostr is not particularly speedy, so that method is presumably not perf sensitive. llvm-svn: 79885
