2020-09-22compiler: call runtime.eqtype for non-interface type switch on aixClément Chigot3-12/+21
All type switch clauses must call runtime.eqtype if the linker isn't able to merge type descriptors pointers. Previously, only interface-type clauses were doing it. Updates golang/go#39276 Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/255202
2020-09-21compiler: finalize methods for type aliases of struct typesIan Lance Taylor3-21/+35
Previously we would finalize the methods of the alias type itself, but since its a type alias we really need to finalize the methods of the aliased type. Also, handle method expressions of unnamed struct types. Test case is https://golang.org/cl/251168. Fixes golang/go#38125 Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/251279

2020-09-17libgo: fix ptrace syscall hooks into glibcPaul E. Murphy1-1/+1
ptrace is actually declared as a variadic function. On ppc64le the ABI requires to the caller to allocate space for the parameters and allows the caller to modify them. On ppc64le, depending on how and what version of GCC is used, it will save to parameter save area. This happened to clobber a saved LR, and caused syscall.TestExecPtrace to fail with a timeout when the tracee segfaults, and waits for the parent process to inspect. Wrap this function to avoid directly calling glibc's ptrace from go. Fixes golang/go#36698 Fixes go/92567 Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/254755

2020-09-14options: Save and restore opts_set for Optimization and Target optionsJakub Jelinek1-3/+5

So, I've tried under debugger how it behaves and seems global_options_set is really an or of whether an option has been ever seen as explicit, either on the command line or in any of the option pragmas or optimize/target attributes seen so far, so it isn't something that can be relied on. The following patch implements the saving/restoring of the opts_set bits (though only for the options/variables saved by the generic options-save.c code, for the target specific stuff that isn't handled by the generic code the opts_set argument is now passed to the hook and the backends can choose e.g. to use a TargetSave variable to save the flags either individually or together in some bitmask (or ignore it if they never need opts_set for the options).

If we lower a constant string operation in a Binary_expression, delete the strings. This is safe because constant strings are always newly allocated. This is a hack to use much less memory when compiling the new time/tzdata package, which has a file that contains the sum of over 13,000 constant strings. We don't do this for numeric expressions because that could cause us to delete an Iota_expression. We should have a cleaner approach to memory usage some day. Fixes PR go/96450

2020-07-27compiler,runtime: pass only ptr and len to some runtime callsIan Lance Taylor3-35/+40
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.
