Patrick Jenkins be25460706 Minor output changes. 
llvm-svn: 29178
 2006-07-18 17:21:30 +00:00
Chris Lattner 692374c748 Completely change the structure of the generated asmprinter to be more table 
based and less switch-statements-with-hundreds-of-cases based.  This shrinks
the x86 asmprinters to about 1/3 their previous size.

Other improvements coming.

Rafael Espindola bf3a17cd32 initial prologue and epilogue implementation. Need to define add and sub before finishing it :-)

Chris Lattner 9c6c94a806 simple optimization: don't bother calling "exists" (which calls the syscall 
"access").  Instead, just let the open call fail if the file doesn't exist.
This reduces the # syscalls executed.

Chris Lattner 4a5641525d Remove a dead conditional: info_ can only be allocated if FD is good. Improve 
spacing

Chris Lattner 7bc8197032 The only entry in the stat buf this code cares about is the size. Keep just 
the size, not the whole stat buffer.

Chris Lattner fe5b7fe6d9 Reduce code in the error path by only allocating info_ if everything looks 
good.

std::map.

Patrick Jenkins a72f84eb39 If a gccpath is specified when invoking the nightly test script we will hopefully now use that gcc for the gcc version. Also fixed some 80 char column stuff.

Evan Cheng 95454e7a2f Use __attribute__((noinline)) only if compiled by gcc.

Evan Cheng 87b2fe9474 Parameterize target node ValueType to allow more sharing of emit functions. 
Also reduce the number of arguments passed to emit functions and removed a
hack.

Evan Cheng 69367fedd2 Reduce instruction selection code size and stack frame size by factoring 
code that emit target specific nodes into emit functions that are uniquified
and shared among selection routines.
e.g. This reduces X86ISelDAGToDAG.o (release) from ~2M to ~1.5M. Stack frame
size of Select_store from ~13k down to ~8k.
This is the first step. Further work to enable more sharing will follow.

Chris Lattner fd5a8ebb74 On 64-bit targets like ppc64, we should use .quad to output pointer directives, 
not .long.

Chris Lattner e1758d4cef Remove what little AIX support we have. It has never been tested and isn't 
complete.

Chris Lattner 45fcadc9f0 The generated index array should be const.

Chris Lattner 2e1d01541a Add an out-of-line virtual method for X86DwarfWriter to give it a home. 
llvm-svn: 29153
 2006-07-14 23:05:05 +00:00
Chris Lattner e32982cc52 Emit the string information for the asm writer as a single large string 
and index into it, instead of emitting it like this:

  static const char * const OpStrs[] = {
    "PHINODE\n",        // PHI
    0,  // INLINEASM
    "adc ",     // ADC32mi
    "adc ",     // ADC32mi8
   ...

The old way required thousands of relocations that slows down link time and
dynamic load times.

This also cuts about 10K off each of the X86 asmprinters, and should shrink
the others as well.

Owen Anderson bea70ee1de Hopefully the final attempt at making IndVars preserve LCSSA.

the same.

Chris Lattner b3c64f7ab3 Handle instructions in the map, but that map to a null pointer. 
This unbreaks smg2000.

Chris Lattner 1ec5e73b32 An overaggressive #ifdef allows a function to fall off the bottom of the 
function instead of returning a value.  This sometimes allowed the ppc32 jit
to be used in 64-bit mode.

Chris Lattner 6148456ec2 In addition to deleting calls, the inliner can constant fold them as well. 
Handle this case, which doesn't require a new callgraph edge.  This fixes
a crash compiling MallocBench/gs.
