2021-02-25libgo: ensure memmove, memset 8 byte atomicity on ppc64xLynn Boger6-6/+143
Go requires that pointer moves are done 8 bytes at a time, but gccgo uses libc's memmove and memset which does not require that, and there are some cases where an 8 byte move might be done as 4+4. To enforce 8 byte moves for memmove and memset, this adds a C implementation in libgo/runtime for memmove and memset to be used on ppc64le and ppc64. Asm implementations were considered but discarded to avoid different implementations for different target ISAs.

2020-12-22runtime: eliminate scase.kind fieldIan Lance Taylor1-40/+53
This is the gofrontend version of https://golang.org/cl/245125. Original CL description: Currently, we include a "kind" field on scase to distinguish the three kinds of cases in a select statement: sends, receives, and defaults. This commit removes by kind field by instead arranging for the compiler to always place sends before receives, and to provide their counts separately. It also passes an explicit "block bool" parameter to avoid needing to include a default case in the array. It's safe to shuffle cases like this because the runtime will randomize the order they're polled in anyway. For golang/go#40410. This is being brought over to gofrontend as a step toward upgrading to Go1.16beta1. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/279735
2020-12-22runtime: add "success" field to sudogIan Lance Taylor3-22/+28
This is the gofrontend version of https://golang.org/cl/245019. Original CL description: The current wakeup protocol for channel communications is that the second goroutine sets gp.param to the sudog when a value is successfully communicated over the channel, and to nil when the wakeup is due to closing the channel. Setting nil to indicate channel closure works okay for chansend and chanrecv, because they're only communicating with one channel, so they know it must be the channel that was closed. However, it means selectgo has to re-poll all of the channels to figure out which one was closed. This commit adds a "success" field to sudog, and changes the wakeup protocol to always set gp.param to sg, and to use sg.success to indicate successful communication vs channel closure. While here, this also reorganizes the chansend code slightly so that the sudog is still released to the pool if the send blocks and then is awoken because the channel closed. For golang/go#40410 This is being brought over to gofrontend as a step toward upgrading to Go1.16beta1, setting up for more compiler changes related to select handling.

This is the gofrontend version of https://golang.org/cl/245123. Original CL description: Currently, selectgo does an initial pass over the cases array to look for entries with nil channels, so they can be easily recognized and skipped later on. But this still involves actually visiting the cases. This commit changes selectgo to omit cases with nil channels when constructing pollorder, so that they'll be skipped over entirely later on. It also checks for caseDefault up front, which will facilitate changing it to use a "block bool" parameter instead.

2020-12-20libgo: adjust sysinfo scripts for changed -fdump-go-specNikhil Benesch3-91/+21
The -fdump-go-spec flag to GCC recently changed to be more fastidious about handling incomplete types. This caused some breakage in mk[r]sysinfo.sh on Solaris. This commit adjusts for the new behavior. Specifically: * Types that refer to _in6_addr may be hidden behind a typedef and can no longer be filtered out with `grep -v in6_addr`. Instead just rewrite the definition of _in6_addr to [16]byte wherever it appears. * timestruc_t is now (correctly) emitted as an alias for timespec, so this case is handled specially. * stdio.h is included in sysinfo.c to avoid emitting an incomplete definition of the FILE type. * Dummy definitions for _u?pad128_t are now emitted automatically, which conflict with the definitions installed by mk[r]sysinfo.sh. These definitions were actually dead code, so just remove them. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/278672
