The actual nicification of calls is now implemented in instcombine, not in
funcresolve

lib/Target/Sparc/Sparc.cpp:
 Move LowerAllocations, PrintFunction, and SymbolStripping passes, and
  the corresponding -disable-strip and -d options, over here to the SPARC
  target-specific bits of llc. Rename -d to -dump-asm.

tools/llc/Makefile:
 Reindent. Add x86 library so that llc compiles again.

tools/llc/llc.cpp:
 Remove support for running arbitrary optimization passes. Use opt instead.
 Remove LowerAllocations, PrintFunction, and SymbolStripping passes, as noted
  above.
 Allow user to select a backend (x86 or SPARC); default to guessing from
  the endianness/pointer size of the input bytecode file.
 Fix typos.
 Delete empty .s file and exit with error status if target does not support
  static compilation.

Move llvm tools to the start of the testrunner path, which allows the llvm 'as'

lib/CWriter/Writer.cpp: Copy AsmWriter's ConstantFP checking code here
into a new function FPCSafeToPrint(), and use it in printConstant()
and printFunction() to decide whether we should output ConstantFPs as

Add #ifdef hack for MAP_ANONYMOUS being spelled MAP_ANON on some platforms.
(We're already talking about autoconf'ing this, so I'm assuming this hack
will be short-lived...I just don't want it to get lost in my working files.)

Use std::isnan instead of isnan.  Brought back to you from the

Life is too short.  Link in too much stuff on Linux to make building on sun easier

The never-ending odyssey trying to get sparc to link

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6747 91177308-0d34-0410-b5e6-96231b3b80d8

Do not link in the Sparc JIT when building on X86.  Eventually the sparc will not
link in the X86 JIT either, but this makes testing easier.

For some reason, the sparc JIT was breaking the X86 JIT when it was linked in. :(

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6745 91177308-0d34-0410-b5e6-96231b3b80d8

Fix bug: Assembler/2003-06-17-InvokeDisassemble.llx

"yes, invoke instructions can have just three arguments"

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6736 91177308-0d34-0410-b5e6-96231b3b80d8

New testcase

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6735 91177308-0d34-0410-b5e6-96231b3b80d8

Fairly major change: emit fixed sized allocas in the entry block as a variable,
instead of a variable pointer and an alloca.  All accesses to the variable then
use the address-of operator to access it.  This plays better with the internal
GCC code generation phases, which bail early on functions which contain allocas.
It also makes the code a bit easier to read.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6734 91177308-0d34-0410-b5e6-96231b3b80d8

Don't corrupt memory when removing an instruction from the program, but
not the worklist

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6733 91177308-0d34-0410-b5e6-96231b3b80d8

Just _EXTEND_ the current path.  Don't replace it.  Replacing it makes it
impossible for scripts to find user tools like sed.

Don't include alloca.h on FreeBSD.

Actually, change it to use explicit new/delete, which is more likely to be

Basically this is the same as Makefile.Linux, at least for now.

Isolate machine-dependent use of <alloca.h> in "Support/Alloca.h",
so that we can easily change its use to be conditional on the result of
an autoconf test later.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6723 91177308-0d34-0410-b5e6-96231b3b80d8

Reconfigured the TOOLS variable so that it points to the current set of tools
built by the LLVM build.
Added a path for use with the TestRunner.sh script so that it can always find
the LLVM tools without having the user place them in his or her path.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6720 91177308-0d34-0410-b5e6-96231b3b80d8

Modified the environment variables that determine where things are located to
do the following:
1) Determine their default values without $HOME
2) Configure the default values as full absolute pathnames.
This should help fix the nightly test builds.

Reverted back to hand-made HTML.
Added in updates for new Makefile variables and corrected some punctuation.

Remove obsolete comments about llvm-ar

Updated the documentation to reflect changes in the Makefiles for building
projects.
Fixed some small grammatical errors.
Using Netscape Composer seems to have added stuff that makes the page look
exactly the same.  Bah!  Curse my laziness!

Changed the LITTLE_ENDIAN and BIG_ENDIAN macros to ENDIAN_LITTLE and ENDIAN_BIG.
This will prevent them from conflicting with macros defined by the system
header files.
When autoconf comes, this will look a lot nicer.

Added assert.h so that it compiles under newer versions of GCC.

Included assert.h so that the code compiles under newer versions of GCC.

Updated to the new Makefile.common.
Modified the test rule so that it can be added to the regular test rule
(I believe the term is double dependency?).

Updated to use the new Makefile.common.
Replaced the hard-coded compiler variable with the one defined by
Makefile.config.

Modified Makefile.common to handle compilation of projects inside and outside
of the llvm source directory.
The main modification was to add new environment variables: one set for llvm
entities and another set for source entities current being compiled.
This should make the Makefile more flexible and easier to understand as each
environment variable only does one thing.

Updated for the new projects Makefile.
