[Bug fortran/79886] [5/6/7 Regression] ICE in pp_format, at pretty-print.c:681
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79886 --- Comment #1 from Manuel López-Ibáñez --- This is probably a warning from the middle end with a printf %-code not supported by the Fortran FE's pretty printer. The solution is to either add support for it in the FE or switch to the middle end pp when entering the middle end. There are several bugs like this one. Another solution is to either not call into the middle end at arbitrary points during parsing only during gimplification (not sure if this is the case here) or move the warning to the FE (middle end warnings should be avoided if possible).

[Bug inline-asm/79880] Gcc refuses to encode vpgatherdd instruction (x86-64)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79880 --- Comment #3 from Jakub Jelinek --- Perhaps something to report to llvm that they accept invalid, that is a bug. Also, why do you use Intel syntax when you don't know how should it be used? In AT&T syntax you wouldn't need to specify this extra stuff, just vpgatherdd %xmm4, (%r13 + %xmm3), %xmm4. Also note that for inline asm you don't specify clobbers etc. (but that might be just from simplification of the testcase).

Change the random walk order for threading in tree-vrp.c to a domwalk I've experimented (not very thoroughly though) with doing the threading during substitute_and_fold via the vrp_fold_stmt callback which is now invoked from a domwalk. > 5. Record data from ASSERT_EXPRs during threading domwalk > > 6. Query the expression hash table in simplify_stmt_for_jump_threading That said, eventually organizing the non-backward threading as a domwalk that uses callbacks to record data / simplify stmts so that it can be used from VRP but also maybe from FRE or other passes that have a useful lattice would be nice. Not sure if all this is appropriate for GCC 7 though.

[Bug lto/79851] diagnostics: replace '%s' with %qs in all diagnostics
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79851 Richard Biener changed: What|Removed |Added Status|UNCONFIRMED |NEW Last reconfirmed||2017-03-06 Ever confirmed|0 |1 --- Comment #1 from Richard Biener --- A complication is that we use two different diagnostic machineries, where I believe only one handles %qs and the other simply uses fprintf (diagnostic*.[ch] vs. errors.[ch]). Some files are build both for generator programs (which use errors.[ch]) and for GCC. For example errors.c simply has /* Similar, but say we got an internal error. */ void internal_error (const char *format, ...) { va_list ap; va_start (ap, format); fprintf (stderr, "%s: Internal error: ", progname); vfprintf (stderr, format, ap); va_end (ap); fputc ('\n', stderr); exit (FATAL_EXIT_CODE); } (so those are also not marked for translation).
[Bug rtl-optimization/79856] rtl_verify_edges: use internal_error instead of error
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79856 --- Comment #2 from Richard Biener --- Note that internal_error will terminate GCC immediately while error () allows for further errors to be diagnosed. Which is what we want here, internal_error is done as the final step in "CFG verification failed" or so.

Hi Andrew, Thanks for the comments. Actually, when we say "--disable-hosted-libstdcxx", we mean that we only want a limited set of headers (same as the one in "freestanding" mode). But as per the info below, "freestanding" mode supports typeinfo and exception headers. In "freestanding" mode only the following headers can be safely used: •cstdarg •cstddef •cstdlib •exception •limits •new •exception •typeinfo

[Bug tree-optimization/79824] [7 Regression] Failure to peel for gaps leads to read beyond mapped memory
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79824 --- Comment #2 from Richard Biener --- Ok, so in the SLP case this is actually safe because we only ever load vectors that end up having at least a single element used (we do not load from unused gaps). In the non-SLP case I botched up the patch, plain interleaving with a single-element is rejected with gaps bigger than vector size (whoo!) and with multi-element I failed to properly use 'first_stmt' for the alignment test and thus we always get peeling for gaps.

Ah, so it will be most likely that DW_AT_const_value: floating-point or vector constant We have: dw_vec_const GTY ((tag ("dw_val_class_vec"))) val_vec; and struct GTY(()) dw_vec_const { unsigned char * GTY((atomic)) array; unsigned length; unsigned elt_size; }; If we are calling strlen on that array, that is obviously incorrect, because the array contains random bytes.

[Bug inline-asm/79880] Gcc refuses to encode vpgatherdd instruction (x86-64)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79880 --- Comment #5 from Jakub Jelinek --- Ah, if you want to avoid the %xmm4, %r13, %xmm3, etc., you need .intel_syntax noprefix. And, the insn is invalid anyway, because you can't have the same mask and destination. In any case, this has nothing to do with gcc, that just passes the text through to gas.
