Misha Brukman a6ecf271db Remove debug code emitter from the JIT

Misha Brukman 2beb63a65a * Added basic support for JITing functions, basic blocks, instruction encoding, 
including registers, constants, and partial support for global addresses
* The JIT is disabled by default to allow building llvm-gcc, which wants to test
  running programs during configure

Nate Begeman 86b5f8075c Don't clear or sign extend bool->int. This fires a few dozen times on the test suite

John Criswell 85b380582e Small performance improvement in generated C code: 
Instead of unconditionally copying all phi node values into temporaries for
all successor blocks, generate code that will determine what successor
block will be called and then copy only those phi node values needed by
the successor block.

This seems to cut down namd execution time from being 8% higher than GCC to
4% higher than GCC.

Misha Brukman e2ada0413e * Add baseline structural JIT code, but disable the JIT to allow llvm-gcc builds 
- Support added for functions, basic blocks, constant pool, constants,
    registers, and some basic support for globals, all untested
* Turn assert()s into abort()s so that unimplemented functions fail in release

Chris Lattner 257b284038 Hrm, some people complain when the compiler cheerfully tells them what it's 
doing... I guess they're right.

Misha Brukman 65af14766f If we're going to make the braces of functions line up for ease of readability 
and aesthetic reasons, might as well finish the job

Brian Gaeke f3499acc16 Simplify mapping info generation. In particular, the LLVM-to-MachineInstr map 
is no longer emitted, and we do not reference any MachineCodeForInstruction
information.

Misha Brukman 9cba8b39be Move code to redefine INT64_{MIN,MAX} on AIX/PowerPC to a separate header, 
because #undef becomes commented out in DataTypes.h.in due to autoheader

Nate Begeman b18121e6a9 Initial implementation of the strength reduction for GEP instructions in 
loops.  This optimization is not turned on by default yet, but may be run
with the opt tool's -loop-reduce flag.  There are many FIXMEs listed in the
code that will make it far more applicable to a wide range of code, but you
have to start somewhere :)

This limited version currently triggers on the following tests in the
MultiSource directory:
pcompress2: 7 times
cfrac: 5 times
anagram: 2 times
ks: 6 times
yacr2: 2 times

Misha Brukman 947cd4569f * AIX on Power defines INT64_MIN and INT64_MAX in ways that annoy GCC, so 
special-case those definitions
* Add comments in #ifdef/#else/#endif clauses for ease of reading

Chris Lattner a67dd32004 Turn store -> null/undef into the LLVM unreachable instruction! This simple 
change hacks off 10K of bytecode from perlbmk (.5%) even though the front-end
is not generating them yet and we are not optimizing the resultant code.
This isn't too bad.

Chris Lattner 3b92f17165 My friend the invoke instruction does not dominate all basic blocks if it 
occurs in the entry node of a function

llvm-svn: 17109
 2004-10-18 01:48:31 +00:00
Chris Lattner 34ae670706 Fix a bug that occurs when the constant value is the result of an invoke. In 
particular, invoke ret values are only live in the normal dest of the invoke
not in the unwind dest.

Chris Lattner 53058663aa Print a semicolon for the unreacahble instruction. This fixes problems 
where C requires semicolons in some cases to indicate null statements.

Chris Lattner 6a792feb02 Getting ADCE to interact well with unreachable instructions seems like a nontrivial 
exercise that I'm not interested in tackling right now.  Just punt and treat them
like unwind's.

This 'fixes' test/Regression/Transforms/ADCE/unreachable-function.ll

Chris Lattner 6e79e55aea Fix Regression/Transforms/Inline/2004-10-17-InlineFunctionWithoutReturn.ll 
If a function had no return instruction in it, and the result of the inlined
call instruction was used, we would crash.

Chris Lattner 107c15c33d Remove printout, realize that instructions in the entry block dominate all 
other blocks.

Chris Lattner 215c7ebaa6 When inserting PHI nodes, don't insert any phi nodes that are obviously 
unneccesary.  This allows us to delete several hundred phi nodes of the
form PHI(x,x,x,undef) from 253.perlbmk and probably other programs as well.

This implements Mem2Reg/UndefValuesMerge.ll
