Nick Lewycky aee2632be3 The memcpy intrinsic only takes i8* for %src and %dst, so cast them to that
first. Fixes PR7265.

Dan Gohman 2140a74979 Eliminate the restriction that the array size in an alloca must be i32.
This will help reduce the amount of casting required on 64-bit targets.

llvm-svn: 104911
2010-05-28 01:14:11 +00:00
Jakob Stoklund Olesen b613ae2c89 Add a -regalloc=default option that chooses a register allocator based on the -O
optimization level.

This only really affects llc for now because both the llvm-gcc and clang front
ends override the default register allocator. I intend to remove that code later.

Devang Patel 91ad65e8b7 Let's try one more time to match patterns.
The goal is to match following 3 lines. In otherwords, a temp. label between to DEBUG_VALUE comments.
        ;DEBUG_VALUE: bar:x <- undef   ## 2010-01-18-Inlined-Debug.c:7
Ltmp1:
        ;DEBUG_VALUE: foo:__x <- undef ## 2010-01-18-Inlined-Debug.c:5

Kevin Enderby 492d4f409a Changed the encoding of X86 floating point stack operations where both operands
are st(0).  These can be encoded using an opcode for storing in st(0) or using
an opcode for storing in st(i), where i can also be 0.  To allow testing with
the darwin assembler and get a matching binary the opcode for storing in st(0)
is now used.  To do this the same logical trick is use from the darwin assembler
in converting things like this:

fmul %st(0), %st

into this:

fmul %st(0)

by looking for the second operand being X86::ST0 for specific floating point
mnemonics then removing the second X86::ST0 operand.  This also has the add
benefit to allow things like:

fmul %st(1), %st

that llvm-mc did not assemble.

Dale Johannesen cd4ba6caba Removing test; Chris thinks it's better to have the
bug go untested than have a testcase this large.  So be it.

this in the suite.  8023512.
