2016-11-15libiberty: demangler crash with missing :? or fold expression component.Mark Wielaard3-0/+19
When constructing an :? or fold expression that requires a third expression only the first and second were explicitly checked to not be NULL. Since the third expression is also required in these constructs it needs to be explicitly checked and rejected when missing. Otherwise the demangler will crash once it tries to d_print the NULL component. Added two examples to demangle-expected of strings that would crash before this fix. Found by American Fuzzy Lop (afl) fuzzer. From-SVN: r242451
2016-11-15libiberty: Fix some demangler crashes caused by reading past end of input.Mark Wielaard3-4/+41
In various situations the cplus_demangle () function could read past the end of input causing crashes. Add checks in various places to not advance the demangle string location and fail early when end of string is reached. Add various examples of input strings to the testsuite that would crash test-demangle before the fixes. Found by using the American Fuzzy Lop (afl) fuzzer. libiberty/ChangeLog: * cplus-dem.c (demangle_signature): After 'H', template function, no success and don't advance position if end of string reached. (demangle_template): After 'z', template name, return zero on premature end of string. (gnu_special): Guard strchr against searching for zero characters.

2016-11-15Use simplify_gen_binary in canon_rtxRichard Sandiford2-7/+7
After simplifying the operands of a PLUS, canon_rtx checked only for cases in which one of the simplified operands was a constant, falling back to gen_rtx_PLUS otherwise. This left the PLUS in a non-canonical order if one of the simplified operands was (plus (reg R1) (const_int X)); we'd end up with: (plus (plus (reg R1) (const_int Y)) (reg R2)) rather than: (plus (plus (reg R1) (reg R2)) (const_int Y)) Fixing this exposed new DSE opportunities on spu-elf in gcc.c-torture/execute/builtins/strcat-chk.c but otherwise it doesn't seem to have much practical effect. gcc/ 2016-11-15 Richard Sandiford <richard.sandiford@arm.com> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> * alias.c (canon_rtx): Use simplify_gen_binary.

2016-11-15Add a load_extend_op wrapperRichard Sandiford8-33/+56
LOAD_EXTEND_OP only applies to scalar integer modes that are narrower than a word. However, callers weren't consistent about which of these checks they made beforehand, and also weren't consistent about whether "smaller" was based on (bit)size or precision (IMO it's the latter). This patch adds a wrapper to try to make the macro easier to use. LOAD_EXTEND_OP is often used to disable transformations that aren't beneficial when extends from memory are free, so being stricter about the check accidentally exposed more optimisation opportunities. "SUBREG_BYTE (...) == 0" and subreg_lowpart_p are implied by paradoxical_subreg_p, so the patch also removes some redundant tests. The patch doesn't change reload, since different checks could have unforeseen consequences. gcc/ 2016-11-15 Richard Sandiford <richard.sandiford@arm.com> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> * rtl.h (load_extend_op): Declare. * rtlanal.c (load_extend_op): New function.

2016-11-15Fix simplify_shift_const_1 handling of vector shiftsRichard Sandiford2-54/+98
simplify_shift_const_1 handles both shifts of scalars by scalars and shifts of vectors by scalars. For vectors this means that each element is shifted by the same amount. However: (a) the two cases weren't always distinguished, so we'd try things for vectors that only made sense for scalars. (b) a lot of the range and bitcount checks were based on the bitsize or precision of the full shifted operand, rather than the mode of each element. Fixing (b) accidentally exposed more optimisation opportunities, although that wasn't the point of the patch. gcc/ 2016-11-15 Richard Sandiford <richard.sandiford@arm.com> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> * combine.c (simplify_shift_const_1): Use the number of bits in the inner mode to determine the range of the shift. When handling shifts of vectors, skip any rules that apply only to scalars.

2016-11-15Move misplaced assignment in num_sign_bit_copies1Richard Sandiford2-2/+9
The old assignment to bitwidth was before we handled VOIDmode with: if (mode == VOIDmode) mode = GET_MODE (x); so when VOIDmode was specified we would always use: if (bitwidth < GET_MODE_PRECISION (GET_MODE (x))) { num0 = cached_num_sign_bit_copies (x, GET_MODE (x), known_x, known_mode, known_ret); return MAX (1, num0 - (int) (GET_MODE_PRECISION (GET_MODE (x)) - bitwidth)); } For a zero bitwidth this always returns 1 (which is the most pessimistic result). gcc/ 2016-11-15 Richard Sandiford <richard.sandiford@arm.com> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> * rtlanal.c (num_sign_bit_copies1): Calculate bitwidth after handling VOIDmode.

2016-11-14runtime: don't crash if signal handler info argument is nilIan Lance Taylor4-4/+16
Apparently on Solaris 10 a SA_SIGINFO signal handler can be invoked with a nil info argument. I would not have believed it but I've now seen it happen, and the sigaction man page actually says "If the second argument is not equal to NULL, it points to a siginfo_t structure...." So, if that happens, don't crash. Also fix another case where we want to make sure that &T{} does not allocate. Reviewed-on: https://go-review.googlesource.com/33150 From-SVN: r242403
