--- Comment #10 from vries at gcc dot gnu.org ---
I've tried out the example from comment 9.
Tree-tail-merge considers the statements without effect because:
...
(gdb) call debug_gimple_stmt (stmt)
# .MEM_10 = VDEF .MEM_3(D)
__asm__(movq $42, %0
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58805
--- Comment #14 from vries at gcc dot gnu.org ---
No it shouldn't. It should return true if the stmt has side-effects that
are _not_ explicit in the statement. This side-effect is explicitely there.
Hmm, a rather deceptive name
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58805
--- Comment #16 from vries at gcc dot gnu.org ---
Btw, you'd have had the same issue with the aggregate
return of a pure/const function call, no?
For this bug to trigger, we need a gimple statement:
- without side-effects
- with one SSA_OP_DEF

thanks for the comments.
Nothing even trying to look at the CFG after freeing it, so the looks at
BLOCK_FOR_INSN in delete_insn are non-sense.

Bug #: 53986
Summary: missing vrp on bit-mask test
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53986
--- Comment #2 from vries at gcc dot gnu.org 2012-07-23 06:29:51 UTC ---
Btw, if the switch is not converted to a bit-test the path to link_error is
also not removed by vrp, because it doesn't handle anti-ranges for switches

--- Comment #16 from vries at gcc dot gnu.org 2012-08-01 21:19:36 UTC ---
With the example from comment 15 and r190039, I don't see a segmentation fault,
but this:
...
$ g++ test.C -O2
test.C: In member function ‘void B::makeLine(int*) const
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50672
--- Comment #17 from vries at gcc dot gnu.org 2012-08-01 23:14:36 UTC ---
The test-case from comment 15 passes with r190033, and fails with r190034.
block 10 contains:
...
# .MEMD.2233_20 = PHI .MEMD.2233_5(11), .MEMD.2233_10(12
