When this method is called through interface, we actually pass the interface data as a pointer. On most platforms this is ok, as the underlying calling convention is the same, except that on SPARC32, the calling convention is actually different. This CL changes the method function actually takes a pointer. The function will convert the pointer to the pointer-shaped receiver type (a no-op conversion from machine code's aspect). For a direct call, in the caller we convert the receiver to a pointer (also no-op conversion) before invoking the method. For an interface call, we pass the pointer as before. This way, it is consistent that we always pass a pointer. Hopefully this fixes SPARC32 build and https://gcc.gnu.org/PR90482.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85429 --- Comment #12 from ian at gcc dot gnu.org --- Author: ian Date: Thu May 31 22:46:52 2018 New Revision: 261045 URL: https://gcc.gnu.org/viewcvs?rev=261045=gcc=rev Log: PR go/85429 Various backports from mainline: libgo: update to Go 1.10.2 release cmd/go: support more Solaris assembler syntaxes Patch by Rainer Orth. cmd/go: update to match recent changes to gc In https://golang.org/cl/111097 the gc version of cmd/go was updated to include some gofrontend-specific changes. The gofrontend code already has different versions of those changes; this CL makes the gofrontend match the upstream code. cmd/go, cmd/vet: make vet work with gccgo Backport https://golang.org/cl/113715 and https://golang.org/cl/113716: cmd/go: don't pass -compiler flag to vet Without this running go vet -compiler=gccgo causes vet to fail. The vet tool does need to know the compiler, but it is passed in vetConfig.Compiler. cmd/go, cmd/vet, go/internal/gccgoimport: make vet work with gccgo When using gccgo/GoLLVM, there is no package file for a standard library package. Since it is impossible for the go tool to rebuild the package, and since the package file exists only in the form of a .gox file, this seems like the best choice. Unfortunately it was confusing vet, which wanted to see a real file. This caused vet to report errors about missing package files for standard library packages. The gccgoimporter knows how to correctly handle this case. Fix this by 1) telling vet which packages are standard; 2) letting vet skip those packages; 3) letting the gccgoimporter handle this case. As a separate required fix, gccgo/GoLLVM has no runtime/cgo package, so don't try to depend on it (as it happens, this fixes golang/go#25324). The result is that the cmd/go vet tests pass when using -compiler=gccgo. crypto/x509: specify path to AIX certificate file go/build, cmd/go: update to match recent changes to gc Several recent changes to the gc version of cmd/go improve the gofrontend support. These changes are partially copies of existing gofrontend differences, and partially new code. This CL makes the gofrontend match the upstream code. The changes included here come from: https://golang.org/cl/111575 https://golang.org/cl/111595 https://golang.org/cl/111635 https://golang.org/cl/111636 For the record, the following recent gc changes are based on code already present in the gofrontend repo: https://golang.org/cl/110915 https://golang.org/cl/111615 For the record, a gc change, partially based on earlier gofrontend work, also with new gc code, was already copied to gofrontend repo in CL 111099: https://golang.org/cl/111097 This moves the generated list of standard library packages from cmd/go/internal/load to go/build. gotools/ChangeLog: Backport from mainline: 2018-05-09 Ian Lance Taylor * Makefile.am (check-go-tool): Don't copy zstdpkglist.go. * Makefile.in: Rebuild.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80128 --- Comment #7 from ian at gcc dot gnu.org --- Author: ian Date: Wed Mar 22 13:59:01 2017 New Revision: 246382 URL: https://gcc.gnu.org/viewcvs?rev=246382=gcc=rev Log: PR go/80128 compiler: check backend alignment for memequalNN functions The code was assuming the usual required alignment for the memequalNN functions (16 bits for int16, 32 for int32, etc.). However, on m68k the required alignment of int32 is only 16 bits. Assuming the memequalNN alignment caused the compiler to incorrectly decide that int32 required a specially generated function rather than calling memequal32. This then crashed if the type descriptor were generated after type-specific functions had been written. Fixes GCC PR 80128.

[Bug go/79037] gccgo: Binaries crash with parforsetup: pos is not aligned on m68k
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79037 --- Comment #14 from ian at gcc dot gnu.org --- Author: ian Date: Wed Feb 1 23:35:59 2017 New Revision: 245110 URL: https://gcc.gnu.org/viewcvs?rev=245110=gcc=rev Log: PR go/79037 Backport from mainline: compiler, runtime: align gc data for m68k The current GC requires that the gc data be aligned to at least a 4 byte boundary, because it uses the lower two bits of the address for flags (see LOOP and PRECISE in runtime/mgc0.c). As the gc data is stored as a [...]uintptr, that is normally always true. However, on m68k, that only guarantees 2 byte alignment. Fix it by forcing the alignment. The parfor code used by the current GC requires that the parfor data be aligned to at least an 8 byte boundary. The code in parfor.c verifies this. This is normally true, as the data uses uint64_t values, but, again, this must be enforced explicitly on m68k. Fixes GCC PR 79037.
