Updated the log of changes (as required by the Burg copyright) to give an
overview of what we changed (which is probably all that the author was looking
for).

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8416 91177308-0d34-0410-b5e6-96231b3b80d8

Modified the code so that we exit() with a non-zero value instead of calling
abort() when we can't open the input filename.  The abort() function generates
a core dump if possible and is meant for handling errors so grand that even the
program knows that debugging is necessary.

Added the .t implicit rule.  You can now run an individual set of QMTests by
specifying "make <test>.t"
For example, make feature.t will run the feature tests.
Removed the QMTESTS variable since it is no longer used.

Checkin of autoconf-style object root.

Copies Makefiles into the new object root directory from the source directory.
Removed the --with-objroot option.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8384 91177308-0d34-0410-b5e6-96231b3b80d8

Checkin of autoconf-style object root.

Updated TestRunner tests so that they work correctly in a separate object root
directory.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8383 91177308-0d34-0410-b5e6-96231b3b80d8

Checkin of autoconf-style object root.

Use QMTest for the feature and Regression tests.
Continue using the Makefile system for the Programs tests.
Adjusted the Makefile rules to handle building outside the source directory.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8381 91177308-0d34-0410-b5e6-96231b3b80d8

Checkin of autoconf-style object root.
Modified Makefiles to use the new Makefile setup in LLVM.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8380 91177308-0d34-0410-b5e6-96231b3b80d8

Checkin of autoconf-style object root.
Adjusted Makefile to work with new autoconf-style object root.
Specifically, use the new -I option of tblgen to find include files.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8379 91177308-0d34-0410-b5e6-96231b3b80d8

Checkin of autoconf-style object root.
Added the AC_CONFIG_MAKEFILE macro to configure akefiles which don't need .in
templates.
Removed the --with-objroot option.
Added commands to configure.ac to configure all of the LLVM Makefiles.  Oof.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8378 91177308-0d34-0410-b5e6-96231b3b80d8

Checkin of autoconf-style object root.
Moved Makefile.common to Makefile.rules.  This makes project Makefiles easier
to support, and allows for easier overriding of default configuration values
that used to be in Makefile.common.
Modified Makefile.config.in to determine paths for directories (like
LLVM_SRC_ROOT) and to use the pwd binary as opposed to the shell builtin (this
works better for symbolic links).

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8377 91177308-0d34-0410-b5e6-96231b3b80d8

Added some optimizations:
* Generate a single BA instead of 6-instruction JUMP if possible
  (this occurs both in the creation and overwriting of the stub code)
* If possible, rewrite the ORIGINAL call to call the generated function
  directly, thus bypassing the stub entirely

Also added some statistics on how often calls are overwritten and how often the
CompilationCallback is invoked.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8376 91177308-0d34-0410-b5e6-96231b3b80d8

Make CreateArgv part of lli rather than part of ExecutionEngine.
Switch Interpreter and JIT's "run" methods to take a Function and a vector of
 GenericValues.
Move (almost all of) the stuff that constructs a canonical call to main()
 into lli (new methods "callAsMain", "makeStringVector").
Nuke getCurrentExecutablePath(), enableTracing(), getCurrentFunction(),
 isStopped(), and many dead decls from interpreter.
Add linux strdup() support to interpreter.
Make interpreter's atexit handler runner and JIT's runAtExitHandlers() look
 more alike, in preparation for refactoring.
atexit() is spelled "atexit", not "at_exit".

Don't return bogus references, and don't add an entry to the Concrete map
unless it's not empty!

Another optimization, speed up the testcase to 2.7s

Removal of explicit stack, which requires the method to be a member (so it can
call setAbstract).  Now that we just compute abstractness we can also return
the computed value by value instead of as an argument.

New method

Remove the "recursive bit", not only is it unused by anyone, it was also
not correctly calculated, and calculating it wrong for fun seems rather
pointless.  This also speeds up my favorite testcase by .25 seconds.

Added code that makes the bytecode file readable (needed by the generated shell
script).
Removed the use of sys/types.h and sys/stat.h.
Modified FileExists() so that it uses the access() system call to check for
file existance.  This requires less header files and might even be a tad bit
faster.

Added a description of the algorithm.
Return failure if the chmod() fails.

Modified the code so that it uses the MakeFileExecutable() method.  The new
library code now adds all execute bits that are allowed by the umask value to
the file's current permission bits.

Added the MakeFileExecutable() method.  This method takes a filename and
gives it execute access while respecting the user's umask.

Don't bother doing an exhaustive recursive walk if we are at the limit of what
we need to know anyway.  This reduces the 2002-07-08-HugePerformanceProblem.llx
down to 3.210u:0.010s, which is back in the acceptable range again

Ugh, fix bugs.  Ok, so the last fix wasn't as great as I thought it was.
Now we're back to: 131.730u, 0.330s, which is still quite an improvement,
but still quite unacceptable

Further simplifications

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8321 91177308-0d34-0410-b5e6-96231b3b80d8

Change the code to no longer compute the "type description" immediately when
the type is analyzed.  Instead, only compute it when requested (with
getDescription), and cached for reuse later.

This dramatically speeds up LLVM in general because these descriptions almost
_never_ need to be constructed.  The only time they are used is when a type is
<<'d.  Printing of modules by themselves uses other code to print symbolic
types when possible, so these descriptions are really only used for debugging.

Also, this fixes the particularly bad case when lots of types get resolved to
each other, such as during linking of large programs.  In these cases, the type
descriptions would be repeatedly recomputed and discarded even though: A. noone
reads the description before it gets resolved, and B. many many resolutions
happen at intermediate steps, causing a HUGE waste of time.

Overall, this makes the getTypeDesc function much more light-weight, and fixes
bug: Assembler/2002-07-08-HugePerformanceProblem.llx, which went from taking
1048.770u/19.150s (which is 17.5 MINUTES, on apoc), to taking 0.020u/0.000s,
which is a nice little speedup.  :)
