2011-09-20 20:20:50 +00:00
Bill Wendling c1da6ea344 When extracting a basic block that ends in an 'invoke' instruction, we need to
extract its associated landing pad block as well. However, that landing pad
block may have more than one predecessor. So split the landing pad block so that
individual landing pads have only one predecessor.

This type of transformation may produce a false positive with bugpoint.

Andrew Trick 52363bdbeb Restore hasPostISelHook tblgen flag.
No functionality change. The hook makes it explicit which patterns
require "special" handling. i.e. it self-documents tblgen
deficiencies. I plan to add verification in ExpandISelPseudos and
Thumb2SizeReduce to catch any missing hasPostISelHooks. Otherwise it's
too fragile.

Andrew Trick 8586e62d91 ARM isel bug fix for adds/subs operands.
Modified ARMISelLowering::AdjustInstrPostInstrSelection to handle the
full gamut of CPSR defs/uses including instructins whose "optional"
cc_out operand is not really optional. This allowed removal of the
hasPostISelHook to simplify the .td files and make the implementation
more robust.

Bill Wendling d3c9d971e6 If we are extracting a basic block that ends in an invoke call, we must also
extract the landing pad block. Otherwise, there will be a situation where the
invoke's unwind edge lands on a non-landing pad.

We also forbid the user from extracting the landing pad block by itself. Again,
this is not a valid transformation.

Nadav Rotem 7ae11279e9 When promoting integer vectors we often create ext-loads. This patch adds a
dag-combine optimization to implement the ext-load efficiently (using shuffles).

For example the type <4 x i8> is stored in memory as i32, but it needs to
find its way into a <4 x i32> register. Previously we scalarized the memory
access, now we use shuffles.

Duncan Sands f2b8c854dd Synthesize x86 max/min instructions also for vectors (i.e. produce
maxps and maxpd).  This broke the sse41-blend.ll testcase by causing
maxpd to be produced rather than a cmp+blend pair, which is the reason
I tweaked it.  Gives a small speedup on doduc with dragonegg when the
GCC vectorizer is used.

  movq  %rbp, %rsp

Since Eric's r123367 commit, the default stack alignment for x86 32-bit
has changed to be 16-bytes. Since then, the MaxStackAlignmentHeuristicPass
hasn't been really used, but with AVX it becomes useful again, since per
ABI compliance we don't always align the stack to 256-bit, but only when
there are 256-bit incoming arguments.

ReserveFP was only used by this pass, but there's no RA target hook that
uses getReserveFP() to check for the presence of FP (since nothing was
triggering the pass to run, the uses of getReserveFP() were removed
through time without being noticed). Change this pass to use
setForceFramePointer, which is properly called by MachineFunction
hasFP method.

The testcase is very big and dependent on RA, not sure if it's worth
adding to test/CodeGen/X86.

Jakob Stoklund Olesen e2c92a3112 Spill mode: Hoist back-copies locally.
The leaveIntvAfter() function normally inserts a back-copy after the
requested instruction, making the back-copy kill the live range.

In spill mode, try to insert the back-copy before the last use instead.
That means the last use becomes the kill instead of the back-copy.  This
lowers the register pressure because the last use can now redefine the
same register it was reading.

This will also improve compile time: The back-copy isn't a kill, so
hoisting it in hoistCopiesForSize() won't force a recomputation of the
source live range.  Similarly, if the back-copy isn't hoisted by the
splitter, the spiller will not attempt hoisting it locally.

2011-09-16 00:03:35 +00:00
Jakob Stoklund Olesen e8339b2e63 Disable local spill hoisting for non-killing copies.
If the source register is live after the copy being spilled, there is no
point to hoisting it.  Hoisting inside a basic block only serves to
resolve interferences by shortening the live range of the source.
