Dan Gohman 3bcd5fe9f1 Use an array instead of a fixed-length std::vector.

Dan Gohman d9911e21df Do a real assert if there is an unhandled vector instruction instead
of just printing to cerr.

Evan Cheng e106e2f142 Enable more fold (sext (load x)) -> (sext (truncate (sextload x)))
transformation. Previously, it's restricted by ensuring the number of load uses
is one. Now the restriction is loosened up by allowing setcc uses to be
"extended" (e.g. setcc x, c, eq -> setcc sext(x), sext(c), eq).

Ted Kremenek ef23e34bba Fixed warning concerning implicit conversion from a NULL pointer
constant to an unsigned int.  We now just directly assign the literal 0.

Ted Kremenek a80b257a21 Renamed internal variables of StmtIteratorBase to make the code
slightly more succinct.

Introduced VariableArrayType* within StmtIteratorBase to (soon)
support iteration over the size expressions of variable length arrays.

Ted Kremenek e2763b0948 Added some comments.
Moved a dependent predicate in an if statement to be an assertion
within the if statement body.

2007-10-29 17:06:35 +00:00
Ted Kremenek 5d18ce750a Added to test case for "self-comparison check" uses of relation operators: x < x and x > x
should emit warnings.

llvm-svn: 43451
2007-10-29 17:02:56 +00:00
Ted Kremenek e451eae8d7 For non-floating point types, added check for expressions of the form
"x == x" and "x != x".  We emit a warning for these since they always evaluate
to a constant value and often indicate a logical error.

Added test case for this check.

Devang Patel d45e055f2c Insetead of assert() just emit an error message for
an unimplemented work  and continue.

2007-10-29 16:56:27 +00:00
Ted Kremenek fa907b8168 For floating point equality check, we now ignore parentheses. e.g.:
(x) == x  is the treated the same as x == x.

llvm-svn: 43448
2007-10-29 16:45:23 +00:00
Ted Kremenek d4ecc6da67 For checking for floating point comparison using == or !=, we now suppress
errors for cases such as "x == x".

Added test case to test this feature.

Chris Lattner c541c3ee15 Model stacksave and stackrestore as both writing memory, since we
don't model their dependences on allocas correctly.  This fixes
PR1745.

Chris Lattner 5c5808a9a3 improve error recovery handling broken 'then' or 'else' stmts in
if statements.  This implements Sema/if-empty-body.c:f3, silencing
a bogus secondary warning.  It also improve the location info for
the nullstmts created for recovery purposes.

Owen Anderson 3692dbe492 Add a first attempt at dominator information for MBB's. Use with caution: this has been tested to compile. It has not yet been confirmed to generate correct analysis.

Chris Lattner 70ae491e42 The callers of ParseStructDeclaration are not expecting it to
eat the terminating ;.  Fix one place where it did, allowing this
to compile without error:

struct x {
 int a;
 union {
  int b;
  float c;
 };

 int d;
};

This reduces diagnostics on PR1750 from 33 to 27.

Chris Lattner 3bc4d20862 casting to void is ok for structs (C99 6.5.4p2), this fixes
one bogus error on PR1750.

Chris Lattner 645ff3ff61 Fix a parser bug on labeled inline asm stmts, allowing us
to parse stuff like:

asm volatile("1:  rex64/fxrstor (%[fx])\n\t"
       "2:\n"
       ".section .fixup,\"ax\"\n"
       "3:  movl $-1,%[err]\n"
       "    jmp  2b\n"
       ".previous\n"
       ".section __ex_table,\"a\"\n"
       "   .align 8\n"
       "   .quad  1b,3b\n"
       ".previous"
       : [err] "=r" (err)
       : [fx] "cdaSDb" (fx), "m" (*fx), "0" (0));

This reduces # diagnostics on PR1750 from 49 to 37.

Chris Lattner 73c56c0735 Implement *skeletal* support for representing GNU inline asm stmts in the AST,
resolving a crash on a .i file in PR1750.  We now generate 49 errors on the
.i file in that bug.

2007-10-29 04:04:16 +00:00
Chris Lattner 1159f065be Fix a major bug in the Type::getAs*Type methods: they didn't strip off
typeof(type) and typeof(expr) correctly.  Now provide a single point of
contact (Type::getDesugaredType) for doing the shallow stripping we need.

Chris Lattner b6fc40e60f I am not sure this is a good idea to be an option, but rename the option for
now.  It conflicts with clang's -pedantic flag.

llvm-svn: 43431
2007-10-29 03:14:55 +00:00
Chris Lattner 5e99fd8c0d Add support for the x86-64 'q' regigster modifier, and add support for the
b/h/w/k/q inline asm memory modifiers, which are just ignored.  This fixes
PR1748 and CodeGen/X86/2007-10-28-inlineasm-q-modifier.ll

Chris Lattner 4a15e04aee Fix PR1752 and LoopSimplify/2007-10-28-InvokeCrash.ll: terminators
can have uses too.  Wouldn't it be nice if invoke didn't exist? :)

Ted Kremenek 8be9bc64ce Fixed assertion in Deserializer::~Deserializer that checks for

Ted Kremenek 387204749b Updated backpatching logic during object deserialization to perform
eager backpatching instead of waithing until all objects have been
deserialized.  This allows us to reduce the memory footprint needed
for backpatching.

Duncan Sands 1826deda68 The guaranteed alignment of ptr+offset is only the minimum of
of offset and the alignment of ptr if these are both powers of
2.  While the ptr alignment is guaranteed to be a power of 2,
there is no reason to think that offset is.  For example, if
offset is 12 (the size of a long double on x86-32 linux) and
the alignment of ptr is 8, then the alignment of ptr+offset
will in general be 4, not 8.  Introduce a function MinAlign,
lifted from gcc, for computing the minimum guaranteed alignment.
I've tried to fix up everywhere under lib/CodeGen/SelectionDAG/.
I also changed some places that weren't wrong (because both values
were a power of 2), as a defensive change against people copying
and pasting the code.
Hopefully someone who cares about alignment will review the rest
of LLVM and fix up the remaining places.  Since I'm on x86 I'm
not very motivated to do this myself...
