Chris Lattner 2e2a0ed7e1 Preselection is _not_ a basicblock pass, because it adds global variables to
the module.  This change converts it from being a basic block pass to being
a simple pass.  This allows elimination of the annotation and simplification
of the logic for moving constants into global variables.

Vikram S. Adve 8264e29e01 When opcodes like ADD were split into reg. and immed. versions (ADDi and ADDr),

Chris Lattner f187b7691d Apparently the dependencies are wrong for this file, so it didn't rebuild it
when changing Instruction.def.  :(

Chris Lattner 6acb1bedb1 Emit x86 instructions for: A = B op C, where A and B are 16-bit registers,
C is a constant which can be sign-extended from 8 bits without value loss,
and op is one of: add, sub, imul, and, or, xor.

This allows the JIT to emit the one byte version of the constant instead of
the two or 4 byte version.  Because these instructions are very common, this
can save a LOT of code space.  For example, I sampled two benchmarks, 176.gcc
and 254.gap.

BM        Old     New    Reduction
176.gcc 2673621 2548962  4.89%
254.gap  498261  475104  4.87%

Note that while the percentage is not spectacular, this did eliminate
124.6 _KILOBYTES_ of codespace from gcc.  Not bad.

Note that this doesn't effect the llc version at all, because the assembler
already does this optimization.

Chris Lattner 97e1b55723 * Rename X86::IMULr16 -> X86::IMULrr16

  extra copy into a register, reducing register pressure.

Chris Lattner bf87734fa0 * Multiplications by 2^X are turned into shifts. This factors code out of the
getelementptr code path for use by other code paths (like malloc and alloca).
* Optimize comparisons with zero
* Generate neg, not, inc, and dec instructions, when possible.

This gives some code size wins, which might translate into performance.  We'll
see tommorow in the nightly tester.

John Criswell 732ae94521 Don't explicitly use $SourceDir to find the tblgen files. This causes make
some confusion when trying to generate files (it probably couldn't tell that
./file and $(SourceDir)/file may be the same file).
Now, just let VPATH find everything, and list the primary tblgen file first in
the list of dependencies so that we can just use $< to reference it in the make
rule.

This should hopefully fix the nightly tester.

llvm-svn: 8433
2003-09-10 14:10:44 +00:00
John Criswell ded9899d2d Updated to find source files using VPATH. This makes writing build rules
much cleaner and easier.
Labeled .td as a suffix for tblgen files in Makefile.rules.
Modified build rules so that source files generated during the build are placed
in the build directory and not the source directory (and not in a Debug
directory).  This makes the system cleaner and allows us to have a read-only
source tree.

Misha Brukman c1ac706afb 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)

  directly, thus bypassing the stub entirely

Chris Lattner 147b66cd2b Add support for the llvm.unwind intrinsic, which we codegen to just do an abort

Add support for the invoke instruction, which codegens just like a call with

The end effect of this change is that programs using the invoke instruction,
but never unwinding, will work fine.  Programs that unwind will abort until
we get unwind support.

Brian Gaeke 02cbe2824c addPassesToJITCompile now takes a FunctionPassManager, to support

Separate addPassesToEmitAssembly from addPassesToJITCompile, because
 the latter requires you to use FunctionPasses, and the former might
 diverge anyway.

Misha Brukman 79226d066e Use the registers g1 and g5 as temporaries for making far jumps and far calls,
because saving i1 and i2 to their ``designated'' stack slots corrupts unknown
memory in other functions, standard libraries, and worse.

In addition, this has the benefit of improving JIT performance because we
eliminate writing out 4 instructions in CompilationCallback() and 2 loads and 2
stores.

Vikram S. Adve 792b48f4d1 1. Bug fix: was using SLL instead of SLLX for ULongTy. Chump.
2. Handle fp-to-uint conversions directly here instead of relying on
   a pre-transformation to replace them with the 2-step conversion.
3. Use size rather than explicitly checking types when deciding what
   opcodes to use, wherever possible.  This is less error prone (the
   bug fix above was not the first time!).
4. Float-to-pointer casts shd now work though this hasn't been tested.

Misha Brukman 4510698acb SparcV9CodeEmitter.cpp:
* Doxygen-ified comments
* Added capability to make far calls (i.e., beyond 30 bits in CALL instr)
  which implies that we need to delete function references that were added by
  the call to addFunctionReference() because the actual call instruction is 10
  instructions away (thanks to 64-bit address construction)
* Cleaned up code that generates far jumps by using an array+loop

SparcV9CodeEmitter.h:
* Explained more of the side-effects of emitFarCall()
