* GVN: Enable value forwarding for callocDuncan P. N. Exon Smith2014-06-121-0/+16
| | | | | | | | | | | | | | | | | | | | | 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. Patch by Philip Reames! llvm-svn: 210828

* CodeGen: enable mov.w/mov.t pairs with minsize for WoASaleem Abdulrasool2014-06-121-1/+6
| | | | | | | | | Windows on ARM uses COFF/PE which is intrinsically position independent. For the case of 32-bit immediates, use a pair-wise relocation as otherwise we may exceed the range of operators. This fixes a code generation crash when using -Oz when targeting Windows on ARM. llvm-svn: 210814

* [llvm-symbolizer] Fix parsing DW_AT_ranges in Fission skeleton compile unit ↵Alexey Samsonov2014-06-121-3/+9
| | | | | | | | | | | | | DIEs. Turns out that DW_AT_ranges_base attribute sets the offset for DW_AT_ranges values specified in the .dwo file, but not for DW_AT_ranges specified in the skeleton compile unit DIE in the main executable. This is extremely confusing, and would hopefully be fixed in DWARF-5 when it's finalized. For now this behavior makes sense, as otherwise Fission would break DWARF consumers who doesn't know anything about DW_AT_ranges_base. llvm-svn: 210809

* Remove pimpl class from PassRegistry.Zachary Turner2014-06-122-99/+26
| | | | | | | | | | | | | | | | | | | Since removeRegistrationListener is no longer called during static destruction, we can get rid of the pimpl in PassRegistry. This should clean up the code somewhat, increase clarity, and also allows us to put the Lock as a member of the class, instead of as a ManagedStatic. As part of this change, the PassInfo class is moved from PassSupport.h to its own file, to eliminate the otherwise circular header dependency between PassRegistry.h and PassSupport.h Reviewed by: rnk, dblaikie Differential Revision: http://reviews.llvm.org/D4107 llvm-svn: 210793

Prior to that only $fcc0 is acceptable. We currently don't optimize (BEQZ (NOT $a), $target) and similar. It's probably best to do this in InstCombine.

* [mips][mips64r6] c.cond.fmt, mov[fntz], and mov[fntz].[ds] are not available ↵Daniel Sanders2014-06-1211-89/+426
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | on MIPS32r6/MIPS64r6 Summary: c.cond.fmt has been replaced by cmp.cond.fmt. Where c.cond.fmt wrote to dedicated condition registers, cmp.cond.fmt writes 1 or 0 to normal FGR's (like the GPR comparisons). mov[fntz] have been replaced by seleqz and selnez. These instructions conditionally zero a register based on a bool in a GPR. The results can then be or'd together to act as a select without, for example, requiring a third register read port. 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 on undefined bits. Later, we will fix this by making the result of SETCC an i64 on MIPS64 targets.
