Chris Lattner 6b7652fae5 Remove a dead function, which died when we got GAS emission working (phwew, 
hold your nose!)

Chris Lattner c927072b50 Implement a simple FIXME: if we are emitting a basic block address that has 
already been emitted, we don't have to remember it and deal with it later,
just emit it directly.

Chris Lattner 2e182fc39b * Merge some win32 ifdefs together 
* Get rid of "emitMaybePCRelativeValue", either we want to emit a PC relative
  value or not: drop the maybe BS.  As it turns out, the only places where
  the bool was a variable coming in, the bool was a dynamic constant.

Chris Lattner 1edd79a1bc Now that we have ghost linkage, we can force resolution of external symbols 
immediately instead of lazily.

In this program, for example:

int main() {
  printf("hello world\n");
  printf("hello world\n");
  printf("hello world\n");
  printf("hello world\n");
}

We used to have to go through compilation callback 4 times (once for each
call to printf), now we don't go to it at all.

Thanks to Misha for noticing this, and for adding the initial ghost linkage
patches.

Chris Lattner b264f7f428 There is no reason to try to materialize the function from bytecode if it 
already has been.  This may be a small speedup.

Chris Lattner 9cc2dac7c1 Add debug-only=jit printout, so we see when lazily resolved symbols are 
set up.

Chris Lattner 3b6bb48c16 Do not emit FunctionBlock blocks for external functions. This shrinks 
bytecode files by about 8 bytes per external function

Chris Lattner 642f8c5ed4 Use a per-function flag bit to indicate whether or not there is a function 
body for the function.

Chris Lattner 7d04cdab77 Make *SURE* to null out the pointer before throwing an exception, otherwise 
the dtor for the BytecodeReader class will try to free it again!

 2004-11-15 21:55:06 +00:00
Chris Lattner 94bd315c3f If a function is external, do not output a FunctionBlock for the function 
AT ALL.  This saves 11 bytes per external function from the bytecode file,
and is also required to make GhostLinkage work.

Chris Lattner 55d85402f6 Make functions default to having external linkage if they have no 
FunctionBlock.

Chris Lattner d18c16b842 Two minor improvements: 
1. Speedup getValueState by having it not consider Arguments.  It's better
    to just add them before we start SCCP'ing.
 2. SCCP can delete the contents of dead blocks.  No really, it's ok!  This
    reduces the size of the IR for subsequent passes, even though
    simplifycfg would do the same job.  In practice, simplifycfg does not
    run until much later than sccp in gccas
