Teach SimplifyCFG about magic pointer constants.2010-02-05T22:03:18ZJakob Stoklund Olesenstoklund@2pi.dk2010-02-05T22:03:18Zurn:sha1:58e9ee85fda5083e2eea987917e8eab6ba31fe5e
Weird code sometimes uses pointer constants other than null. This patch
teaches SimplifyCFG to build switch instructions in those cases.
Code like this:
void f(const char *x) {
if (!x)
puts("null");
else if ((uintptr_t)x == 1)
puts("one");
else if (x == (char*)2 || x == (char*)3)
puts("two");
else if ((intptr_t)x == 4)
puts("four");
else
puts(x);
}
Now becomes a switch:
define void @f(i8* %x) nounwind ssp {
entry:
%magicptr23 = ptrtoint i8* %x to i64 ; <i64> [#uses=1]
switch i64 %magicptr23, label %if.else16 [
i64 0, label %if.then
i64 1, label %if.then2
i64 2, label %if.then9
i64 3, label %if.then9
i64 4, label %if.then14
]
Note that LLVM's own DenseMap uses magic pointers.

Implement PR5795 by merging duplicated return blocks. This could go further2009-12-22T06:07:30ZChris Lattnersabre@nondot.org2009-12-22T06:07:30Zurn:sha1:1a0e7081c3e94ae69f2768465da34a3dceaaa5f6
by merging all returns in a function into a single one, but simplifycfg
currently likes to duplicate the return (an unfortunate choice!)

auto-update the DominatorTree because it doesn't keep the DominatorTree
current while it works.

MergeBlockIntoPredecessor. This makes SimplifyCFG slightly more aggressive,
and makes it unnecessary for LoopUnroll to have its own copy of this code.
