Chris Lattner ec3f094489 Fix problems running the HowToUseJIT on powerpc, and probably problems with 
ANY program that does not have all functions internalized.

Chris Lattner 5326f35715 Rework constant pool handling so that function constant pools are no longer 
leaked to the system.  Now they are destroyed with the JITMemoryManager is
destroyed.

Reid Spencer cbd791c5e7 Be double sure about including sys/stat.h by wrapping the inclusion in 
an "#if defined(HAVE_SYS_STAT_H)".

Reid Spencer 181cf4ce17 Move the #include of sys/stat.h inside the linux "hack" for the stat 
family of functions so it gets noticed if we ever remove this.

llvm-svn: 19022
 2004-12-17 19:09:16 +00:00
Reid Spencer 0575a63578 Only #include sys/stat.h if we're on linux where we have the PR274 problem.

Chris Lattner 5a4dc8ca5a Do not look here for elegance. 
This fixes the ugly darwin "cannot find symbols starting with __" issue.

Thanks for Owen/resistor for testing this out for me.

Chris Lattner 65f6638822 Allow targets to avoid emitting a stub for EVERY lazily resolved call. In 
most cases (e.g. direct calls) no stub is needed.

Chris Lattner c27389815d Match change in MachineCodeEmitter prototype. 
llvm-svn: 18009
 2004-11-19 20:56:46 +00:00
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.

Brian Gaeke 9a51b8ca7c When emitting debug msgs for function stubs, don't truncate the 
printed pointer value if sizeof(unsigned) != pointer size.  Instead,
use uintptr_t.

Chris Lattner 8267b7e17d Goodbye macro hell, hello nice clean simple extensible code. This change 
also gives the JIT the ability to dynamically load targets. e.g.

lli -load libparisc.so -march=parisc foo.bc
