2020-08-27gotest: use a space rather than a middle dot in target listsMaciej W. Rozycki1-2/+2
Replace the U+00B7 middle dot character, placed after "mips64p32le" in the target lists, with a space. The U+00B7 character may not be considered whitespace by Bourne shell and any non-ASCII character may render incorrectly in some terminal devices.

2020-08-10runtime: revert eqtype for AIXClément Chigot4-11/+64
AIX linker is not able to merge identical type descriptors in a single symbol if there are coming from different object or shared object files. This results into several pointers referencing the same type descriptors. Thus, eqtype is needed to ensure that these different symbols will be considered as the same type descriptor. Fixes golang/go#39276 gcc/go/ChangeLog: * go-c.h (struct go_create_gogo_args): Add need_eqtype field. * go-lang.c (go_langhook_init): Set need_eqtype.

2020-07-27compiler,runtime: pass only ptr and len to some runtime callsIan Lance Taylor5-63/+68
This ports https://golang.org/cl/227163 to the Go frontend. This is a step toward moving up to the go1.15rc1 release. Original CL description: cmd/compile,runtime: pass only ptr and len to some runtime calls Some runtime calls accept a slice, but only use ptr and len. This change modifies most such routines to accept only ptr and len. After this change, the only runtime calls that accept an unnecessary cap arg are concatstrings and slicerunetostring. Neither is particularly common, and both are complicated to modify. Negligible compiler performance impact. Shrinks binaries a little. There are only a few regressions; the one I investigated was due to register allocation fluctuation. Passes 'go test -race std cmd', modulo golang/go#38265 and golang/go#38266.

2020-01-02compiler, runtime, reflect: generate hash functions only for map keysIan Lance Taylor12-224/+315
Right now we generate hash functions for all types, just in case they are used as map keys. That's a lot of wasted effort and binary size for types which will never be used as a map key. Instead, generate hash functions only for types that we know are map keys. Just doing that is a bit too simple, since maps with an interface type as a key might have to hash any concrete key type that implements that interface. So for that case, implement hashing of such types at runtime (instead of with generated code). It will be slower, but only for maps with interface types as keys, and maybe only a bit slower as the aeshash time probably dominates the dispatch time. Reorg where we keep the equals and hash functions. Move the hash function from the key type to the map type, saving a field in every non-map type. That leaves only one function in the alg structure, so get rid of that and just keep the equal function in the type descriptor itself. While we're here, reorganize the rtype struct to more closely match the gc version. This is the gofrontend version of https://golang.org/cl/191198.
