Cameron Zwarich 341c36dc8b Change the signext language in LangRef to closer match zeroext.

Cameron Zwarich ac106273d4 The x86-64 ABI says that a bool is only guaranteed to be sign-extended to a byte
rather than an int. Thankfully, this only causes LLVM to miss optimizations, not
generate incorrect code.

This just fixes the zext at the return. We still insert an i32 ZextAssert when
reading a function's arguments, but it is followed by a truncate and another i8
ZextAssert so it is not optimized.

Nadav Rotem 25f2ac948b Fix 9267; Add vector zext support.
The DAGCombiner folds the zext into complex load instructions. This patch
prevents this optimization on vectors since none of the supported targets
knows how to perform load+vector_zext in one instruction.

Jakob Stoklund Olesen d3438eb27d Don't document exactly how virtual registers are represented as integers. Code
shouldn't depend directly on that.

Give an example of how to iterate over all virtual registers in a function
without depending on the representation.

llvm-svn: 123099
2011-01-08 23:10:59 +00:00
Rafael Espindola 45e6c195d7 First step in fixing PR8927:
Add a unnamed_addr bit to global variables and functions. This will be used
to indicate that the address is not significant and therefore the constant
or function can be merged with others.

If an optimization pass can show that an address is not used, it can set this.

Examples of things that can have this set by the FE are globals created to
hold string literals and C++ constructors.

Adding unnamed_addr to a non-const global should have no effect unless
an optimization can transform that global into a constant.

Aliases are not allowed to have unnamed_addr since I couldn't figure
out any use for it.

Nick Lewycky 80b2e8151e Further expand what a call graph pass may do.
The rationale is that after analyzing a function in the SCC, we may want to
modify it in a way that requires us to update its uses (f.e. to replace the
call with a constant) or its users (f.e. to call it with fewer arguments).

David Greene a93adab324 Fix PR 8199. This patch prepends the build tool dir to LLVM programs

makes LLVM testing much more stable and predictable.

revision id is appended to the LLVM version string. Defaults to

Until now the VC revision id was always appended to the revision

because a cmake source file changed). This was causing massive
recompilations because config.h are reconfigured with the new contents
of PACKAGE_VERSION.

even though it didn't reach MustAlias or NoAlias.

Chris Lattner 79ffdc7581 With the newly simplified SourceMgr interfaces and the generalized
SrcMgrDiagHandler, we can improve clang diagnostics for inline asm:
instead of reporting them on a source line of the original line,
we can report it on the correct line wherever the string literal came
from. For something like this:

void foo() {
  asm("push %rax\n"
      ".code32\n");
}

we used to get this: (note that the line in t.c isn't helpful)

t.c:4:7: error: warning: ignoring directive for now
  asm("push %rax\n"
      ^
<inline asm>:2:1: note: instantiated into assembly here
.code32
^

now we get:

t.c:5:8: error: warning: ignoring directive for now
      ".code32\n"
       ^
<inline asm>:2:1: note: instantiated into assembly here
.code32

Chris Lattner 2cb092dc55 Implement (and document!) support for MnemonicAlias's to have Requires
directives, allowing things like this:

def : MnemonicAlias<"pop", "popl">, Requires<[In32BitMode]>;
def : MnemonicAlias<"pop", "popq">, Requires<[In64BitMode]>;

Move the rest of the X86 MnemonicAliases over to the .td file.
