Evan Cheng 77c545e6b8 Under normal circumstances, when a frame pointer is not required, we reserve
argument space for call sites in the function immediately on entry to the
current function. This eliminates the need for add/sub sp brackets around call
sites. However, this is not always a good idea. If the "call frame" is large and
the target load / store instructions have small immediate field to encode sp
offset, this can cause poor codegen. In the worst case, this can make it
impossible to scavenge a register if the reserved spill slot is pushed too far
apart from sp / fp.

produce two results.)

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.

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
loops on these tests:
