Dan Gohman d006ab90dd Generalize IVUsers to track arbitrary expressions rather than expressions
explicitly split into stride-and-offset pairs. Also, add the
ability to track multiple post-increment loops on the same expression.

This refines the concept of "normalizing" SCEV expressions used for
to post-increment uses, and introduces a dedicated utility routine for
normalizing and denormalizing expressions.

This fixes the expansion of expressions which are post-increment users
of more than one loop at a time. More broadly, this takes LSR another
step closer to being able to reason about more than one loop at a time.

2010-04-07 21:52:48 +00:00
Sean Callanan 1efe661b46 Fixed a bug where the disassembler would allow an immediate
argument that had to be between 0 and 7 to have any value,
firing an assert later in the AsmPrinter.  Now, the
disassembler rejects instructions with out-of-range values
for that immediate.

ARMDecoderEmitter.cpp, with FIXME comment.

Chris Lattner b35583df52 add a new driver-level -ferror-limit=412 option, which causes clang to stop
emitting diagnostics after it has produced that many errors.  Give this a
default value of 20 which produces plenty of errors for people to fix before
recompiling but not so many that their entire console scrolls away when the
compiler gets confused.  The experience looks like this:

$ clang foo.c
<tons of crap>
foo.c:102:3: error: unknown type name 'somethingbad'
  somethingbad x;
  ^
fatal error: too many errors emitted, stopping now
36 warnings and 20 errors generated.

Dale Johannesen f118f9788b Split big test into multiple directories to cater to
those who don't build all targets.

Douglas Gregor fd27fed584 Return early from Sema::MarkDeclarationReferenced when we know there
isn't any extra work to perform. Also, don't check for unused
parameters when the warnings will be suppressed anyway. Improves
performance of -fsyntax-only on 403.gcc's combine.c by ~2.5%.

Sean Callanan 643a55708f Added an AsmLexer for the ARM target, which uses
a simple mapping of register names to IDs to
identify register tokens.

2010-04-07 20:29:34 +00:00
Chris Lattner 75a0393eb5 add capabilities to stop emitting errors after some limit.
Right now the limit is 0 (aka disabled)

Ted Kremenek 43a9c9626f Don't emit an 'unused expression' warning for '||' and '&&' expressions that contain assignments
or similar side-effects.

Chris Lattner 198cb4df6e Instead of counting totally diagnostics, split the count into a count
of errors and warnings.  This allows us to emit something like this:

2 warnings and 1 error generated.

instead of:

3 diagnostics generated.

This also stops counting 'notes' because they are just follow-on information
about the previous diag, not a diagnostic in themselves.

2010-04-07 18:20:18 +00:00
Anton Korobeynikov 7d4fad5942 VHADD differs from VHSUB at least on A9 - the former reads both operands in the second cycle, while the latter reads second operand in first cycle. Introduce new itin classes to catch this behavior. Whether this is true for A8 as well is WIP.
