GVN: Enable value forwarding for calloc

Enable value forwarding for loads from `calloc()` without an intervening
store.

This change extends GVN to handle the following case:

    %1 = tail call noalias i8* @calloc(i64 1, i64 4)
    %2 = bitcast i8* %1 to i32*
    ; This load is trivially constant zero
    %3 = load i32* %2, align 4

This is analogous to the handling for `malloc()` in the same places.
`malloc()` returns `undef`; `calloc()` returns a zero value.  Note that
it is correct to return zero even for out of bounds GEPs since the
result of such a GEP would be undefined.

mov[fntz].[ds] have been replaced with sel.[ds]

MIPS64r6 currently generates unnecessary sign-extensions for most selects.
This is because the result of a SETCC is currently an i32. Bits 32-63 are
undefined in i32 and the behaviour of seleqz/selnez would otherwise depend

Summary:
The accumulator-based (HI/LO) multiplies and divides from earlier ISA's have
been removed and replaced with GPR-based equivalents. For example:
  div $1, $2
  mflo $3

  div $3, $1, $2

This patch disables the accumulator-based multiplies and divides for
MIPS32r6/MIPS64r6 and uses the GPR-based equivalents instead.

Renamed expandPseudoDiv to insertDivByZeroTrap to better describe the
behaviour of the function.

MipsDelaySlotFiller now invalidates the liveness information when moving
instructions to the delay slot. Without this, divrem.ll will abort since
%GP ends up used before it is defined.

10 years agoUse std::error_code instead of llvm::error_code.
Rafael Espindola [Wed, 11 Jun 2014 19:05:50 +0000 (19:05 +0000)]
Use std::error_code instead of llvm::error_code.

The idea of this patch is to turn llvm/Support/system_error.h into a
transitional header that just brings in the erorr_code api to the llvm
namespace. I will remove it shortly afterwards.

The cases where the general idea needed some tweaking:

* std::errc is a namespace in msvc, so we cannot use "using std::errc". I could
add an #ifdef, but there were not that many uses, so I just added std:: to
them in this patch.

* Template specialization had to be moved to the std namespace in this
patch set already.

* The msvc implementation of default_error_condition doesn't seem to
provide the same transformations as we need. Not too surprising since
the standard doesn't actually say what "equivalent" means. I fixed the
problem by keeping our old mapping and using it at error_code
construction time.

Despite these shortcomings I think this is still a good thing. Some reasons:

* The different implementations of system_error might improve over time.
* It removes 925 lines of code from llvm already.
* It removes 6313 bytes from the text segment of the clang binary when
it is built with gcc and 2816 bytes when building with clang and
libstdc++.
