2020-10-15tree-optimization/97482 - fix split_constant_offset of nop-conversionsRichard Biener3-1/+48
split_constant_offset is confused about a nop-conversion from unsigned long to sizetype and tries to prove non-overflowing of the inner operation. Obviously the conversion could have been elided so make sure split_constant_offset handles this properly. It also makes sure that convert_to_ptrofftype does not introduce conversions not necessary which in this case is the source for the unnecessary conversion. 2020-10-15 Richard Biener <rguenther@suse.de> PR tree-optimization/97482 * tree-data-ref.c (split_constant_offset_1): Handle trivial conversions better. * fold-const.c (convert_to_ptrofftype_loc): Elide conversion if the offset is already ptrofftype_p. * gcc.dg/vect/pr97428.c: New testcase.

2020-10-14libgo: export NetBSD-specific types in mksysinfo.shNikhil Benesch1-1/+1
The syscall package depends on many NetBSD-specific types on NetBSD. Teach mksysinfo.sh to export these types. This alone is not sufficient to get the syscall package to compile on NetBSD, but it's a start. Note that the IfMsgHdr type is recapitalized to IfMsghdr, which requires changes in the AIX port. The new capitalization is what's used by upstream in existing NetBSD-specific code and is more consistent with the capitalization of other C structs with the "hdr" suffix. Updates golang/go#38538.

2020-10-14runtime: correct semaphore implementation on netbsdNikhil Benesch1-1/+1
NetBSD's semaphores use the underlying lighweight process mechanism (LWP) on NetBSD, rather than pthreads. This means the m.prodcid needs to be set to the LWP ID rather than the pthread ID in order for unpark notifications to get sent to the right place. Introduce a new getProcID() method that selects the correct ID for the platform. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/261742
