[Bug c/63233] Missing Warray-bounds warning for array within struct
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63233 --- Comment #6 from Mikael Pettersson mikpelinux at gmail dot com --- (In reply to leis from comment #5) Fundamentally, what I'm really trying to do, is to have two arrays (of different types) in a fixed-sized struct. One array grows from the front, and one from the end. Dynamically I make sure that they do not overlap, but the sizes of the two arrays are not known statically. Is it really violating the standard? Something like union u { int a[50]; char b[50 * sizeof int]; }; and accessing one array with incrementing indices and the other with decrementing indices should work, if I understand your problem statement correctly. But this is now about programming not a gcc bug, so please use gcc-help or some general C programming forum instead.

Nominally, we return 5 to 8 byte aggregate values in a BLKmode because of the odd right justification of the object. However in this case, we have a DFmode aggregate and treating it as BLKmode causes the ICE.

[Bug target/63260] New: [SH] fabs, fneg do not need fp-mode setting and do not use fpscr
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63260 Bug ID: 63260 Summary: [SH] fabs, fneg do not need fp-mode setting and do not use fpscr Product: gcc Version: 5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: olegendo at gcc dot gnu.org Target: sh*-*-* Created attachment 33490 -- https://gcc.gnu.org/bugzilla/attachment.cgi?id=33490action=edit Proposed patch The fabs and fneg insns do not require an FPSCR.PR or FPSCR.SZ mode setting as they operate on the high part of a double register pair. Thus they are the same for single and double precision
