2008-07-21 20:02:45 +00:00
Dan Gohman 581cc87f57 Add titles to the various SelectionDAG viewGraph calls
that include useful information like the name of the
block being viewed and the current phase of compilation.

Bruno Cardoso Lopes e5d1fcfe4e Added initial support for small sections on Mips.
Added gp_rel relocations to support addressing small section contents.
Added command line to specify small section threshold in bytes.

Duncan Sands b0e3938651 Add VerifyNode, a place to put sanity checks on
generic SDNode's (nodes with their own constructors
should do sanity checking in the constructor).  Add
sanity checks for BUILD_VECTOR and fix all the places
that were producing bogus BUILD_VECTORs, as found by
"make check".  My favorite is the BUILD_VECTOR with
only two operands that was being used to build a
vector with four elements!

Evan Cheng e001643358 Use movaps instead of movups to spill 16-byte vector values when default alignment is >= 16. This fixes some massive performance regressions.

into v4i16 vectors.

Anton Korobeynikov bc780e3441 Unbreak build: 'DarwinTargetAsmInfo' was already taken as PPC TAI flavour.

Duncan Sands 2a28791789 Make sure custom lowering for LegalizeTypes
returns a node with the right number of
return values.  This fixes codegen of
Generic/cast-fp.ll, Generic/fp_to_int.ll
and PowerPC/multiple-return-values.ll
when using -march=ppc32 -mattr=+64bit.

Dan Gohman 44dfd7bf56 In the CBackend, use casts to force integer add, subtract, and
multiply to be done as unsigned, so that they have well defined
behavior on overflow. This fixes PR2408.

llvm-svn: 53767
2008-07-18 18:43:12 +00:00
Dan Gohman 1705968102 Add a new function, ReplaceAllUsesOfValuesWith, which handles bulk
replacement of multiple values. This is slightly more efficient
than doing multiple ReplaceAllUsesOfValueWith calls, and theoretically
could be optimized even further. However, an important property of this
new function is that it handles the case where the source value set and
destination value set overlap. This makes it feasible for isel to use
SelectNodeTo in many very common cases, which is advantageous because
SelectNodeTo avoids a temporary node and it doesn't require CSEMap
updates for users of values that don't change position.

Revamp MorphNodeTo, which is what does all the work of SelectNodeTo, to
handle operand lists more efficiently, and to correctly handle a number
of corner cases to which its new wider use exposes it.

This commit also includes a change to the encoding of post-isel opcodes
in SDNodes; now instead of being sandwiched between the target-independent
pre-isel opcodes and the target-dependent pre-isel opcodes, post-isel
opcodes are now represented as negative values. This makes it possible
to test if an opcode is pre-isel or post-isel without having to know
the size of the current target's post-isel instruction set.

These changes speed up llc overall by 3% and reduce memory usage by 10%
on the InstructionCombining.cpp testcase with -fast and -regalloc=local.

2008-07-15 02:03:36 +00:00
Bruno Cardoso Lopes 80ab8f9649 Added Subtarget support into RegisterInfo
Added HasABICall and HasAbsoluteCall (equivalent to gcc -mabicall and 
-mno-shared). HasAbsoluteCall is not implemented but HasABICall is the 
default for o32 ABI. Now, both should help into a more accurate 
relocation types implementation. 
Added IsLinux is needed to choose between asm directives.
Instruction name strings cleanup.
AsmPrinter improved.
