Chris Lattner b58f93f273 Clean up multi-line asam string printing. Instead of printing: 
# InlineAsm Start
        subfc r3,r5,r4
                subfze r4,r3
        # InlineAsm End

print:

Reid Spencer 8d4ff90680 If an archive is not recognized as an LLVM bytecode archive then declare 
that it is native so that the linker will pass it on downstream. This avoids
a problem where the native link line fails because there is both a .so and
a .a file. The .a file gets processed as bytecode and then dropped from the
command line.

llvm-svn: 36580
 2007-04-29 21:49:05 +00:00
Chris Lattner 3543caacd3 Implement much expanded dumper support. We now print stuff like: 
<MODULE_BLOCK NumWords=27 BlockCodeSize=3>
  <TYPE_BLOCK NumWords=7 BlockCodeSize=4>
    <NUMENTRY op0=7>
    <POINTER op0=1>
    <FUNCTION op0=0 op1=2 op2=2 op3=2 op4=2>
    <VECTOR op0=2 op1=3>
    <INTEGER op0=64>
    <VECTOR op0=8 op1=5>
    <INTEGER op0=16>
    <VOID>
...

With work, the operands can be pretty printed symbolically.

llvm-svn: 36555
 2007-04-29 08:05:07 +00:00
Chris Lattner 6694f60bec Switch the bitcode reader interface to take a MemoryBuffer instead of knowing 
anything about disk I/O itself.  This greatly simplifies its interface -
eliminating the need for the ReaderWrappers.cpp file.

This adds a new option to llvm-dis (-bitcode) which instructs it to read
the input file as bitcode.  Until/unless the bytecode reader is taught to
read from MemoryBuffer, there is no way to handle stdin reading without it.

I don't plan to switch the bytecode reader over, I'd rather delete it :),
so the option will stay around temporarily.

Chris Lattner 401d8db381 memory operands that have a direct operand should have their stores created 
before the copies into physregs are done.  This avoids having flag operands
skip the store, causing cycles in the dag at sched time.  This fixes infinite

Chris Lattner 827cb98a0a If an alloca only has two types of uses: 1) reads 2) a memcpy/memmove that 
copies from a constant global, then we can change the reads to read from the
global instead of from the alloca.  This eliminates the alloca and the memcpy,
and promotes secondary optimizations (because the loads are now loads from
a constant global).

This is important for a common C idiom:

void foo() {
   int A[] = {1,2,3,4,5,6,7,8,9...};
   ... only reads of A ...
}

For some reason, people forget to mark the array static or const.

This triggers on these multisource benchmarks:
JM/ldecode: block_pos, [3 x [4 x [4 x i32]]]
FreeBench/mason: m, [18 x i32], inlined 4 times

MiBench/office-stringsearch: find_strings, [1333 x i8*]

and these spec benchmarks:
