Andrew Trick 55aeb55aa3 Bugpoint support for miscompilations that result in a crash.
This change allows bugpoint to pinpoint the "opt" pass and bitcode
segment responsible for a crash caused by miscompilation. At least it
works well for me now, without having to create any custom execution
wrappers.

Andrew Trick 8665d59f46 Added bugpoint options: -compile-custom and -compile-command=...
I've been using this mode to narrow down llc unit tests. Example
custom compile script:
llc "$@"
not pygrep.py 'mul\s+r([0-9]), r\1,' < bugpoint-test-program.s

Duncan Sands e9cd6d069d Apply timeouts and memory limits in more places. In particular, when
bugpoint does "Running the code generator to test for a crash" this
gets you a crash if llc goes into an infinite loop or uses up vast
amounts of memory.

Chris Lattner fd381328ff add support for bugpointing the integrated assembler. Something like this
works for me: bugpoint Output/bisort.llvm.bc -run-llc-ia -safe-run-llc

This uses llc with the integrated assembler as the test compiler and llc
without it as the safe compiler.

Daniel Dunbar a53337f731 Add -output-prefix option to bugpoint (to change the default output name).
llvm-svn: 81154
2009-09-07 19:26:11 +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.

Dan Gohman 46ffffa750 Fix FindExecutable to use sys::Path::GetMainExecutable instead of
just argv[0]. And remove the code for searching the current
working directory and for searching PATH; the point of FindExecutable
is not to find whatever version of the executable can be found by
searching around, but to find an executable that accompanies the
current executable.

Update the tools to use sys::Program::FindProgramByName when they
want PATH searching.

Bill Wendling bf5d827194 Add a "-gcc-tool-args" option. This option acts like the "-tool-args" option,
but passes the arguments to the "gcc" invocation instead of to the "llc"
invocation.

Dan Gohman 414cf50234 Generalize bugpoint's concept of a "safe" backend, and add options
to allow the "safe" backend to be run with a different path, and/or
with different command-line options.

This enables the following use cases:
 - bugpoint llc against an llc command from a different build
 - bugpoint llc against the same llc with different command-line options
 - and more...

Also, document the existing "custom" interpreter options.

Reid Spencer d077fe70e9 Add an -append-exit-code option to bugpoint. This will cause bugpoint to
append "exit <retcode>" to the end of the output file. This is used by
the nightly tester to make bugpoint match the output generated by the
RunSafely.sh script so it doesn't find false positives.

Chris Lattner f1a1a7ae6f add a new bugpoint mode -llc-safe. This uses LLC for both halves of a
miscompilation.  This is useful for working around GCC+CBE bugs or for handling
programs that CBE doesn't support (e.g. inline asm) when searching for
optimizer bugs.

Patrick Jenkins c46c03834c This commit adds a new feature called find-bugs. The find-bugs option can be invoked on a .bc file from the command like with -find-bugs and a list of passes you wish to test. This procedure takes the set of optimization passes the user specifies, randomizes the passes, runs the passes on the specified .bc file, compiles the program, and finally runs the program checking its output vs the .bc file with no optimizations. This process repeats until either the user kills bugpoint or an error occurs in the optimizations, program complitation, or the running of the program. If an error occurs, bugpoint attempts to diagnose the error by eliminating passes that are not at fault and code that is not needed.

Reid Spencer c3065b7d3f Add the -Xlinker option to bugpoint which allows an option to be passed
through to gcc when its being used as a linker. This allows -L and -l
(and any other) options to be added so that non-complete bytecode files
can be processed with bugpoint. The -Xlinker option can be added as many
times as needed.

Reid Spencer af48d8643d Final Changes For PR495:
This chagne just renames some sys::Path methods to ensure they are not
misused. The Path documentation now divides methods into two dimensions:
Path/Disk and accessor/mutator. Path accessors and mutators only operate
on the Path object itself without making any disk accesses. Disk accessors
and mutators will also access or modify the file system. Because of the
potentially destructive nature of disk mutators, it was decided that all
such methods should end in the work "Disk" to ensure the user recognizes
that the change will occur on the file system. This patch makes that
change. The method name changes are:

makeReadable        -> makeReadableOnDisk
makeWriteable       -> makeWriteableOnDisk
makeExecutable      -> makeExecutableOnDisk
setStatusInfo       -> setStatusInfoOnDisk
createDirectory     -> createDirectoryOnDisk
createFile          -> createFileOnDisk
createTemporaryFile -> createTemporaryFileOnDisk
destroy             -> eraseFromDisk
rename              -> renamePathOnDisk

These changes pass the Linux Deja Gnu tests.

Reid Spencer c9c0473fa5 For PR495:
Get rid of the difference between file paths and directory paths. The Path
class now simply stores a path that can refer to either a file or a
directory. This required various changes in the implementation and interface
of the class with the corresponding impact to its users. Doxygen comments were
also updated to reflect these changes. Interface changes are:

appendDirectory -> appendComponent
appendFile -> appendComponent
elideDirectory -> eraseComponent
elideFile -> eraseComponent
elideSuffix -> eraseSuffix
renameFile -> rename
setDirectory -> set
setFile -> set

Changes pass Dejagnu and llvm-test/SingleSource tests.
