2017-01-14libgo: update to Go 1.8 release candidate 1Ian Lance Taylor1-0/+28
Compiler changes: * Change map assignment to use mapassign and assign value directly. * Change string iteration to use decoderune, faster for ASCII strings. * Change makeslice to take int, and use makeslice64 for larger values. * Add new noverflow field to hmap struct used for maps. Unresolved problems, to be fixed later: * Commented out test in go/types/sizes_test.go that doesn't compile. * Commented out reflect.TestStructOf test for padding after zero-sized field. Reviewed-on: https://go-review.googlesource.com/35231 gotools/: Updates for Go 1.8rc1. * Makefile.am (go_cmd_go_files): Add bug.go. (s-zdefaultcc): Write defaultPkgConfig. * Makefile.in: Rebuild.

2015-01-15libgo, compiler: Upgrade libgo to Go 1.4, except for runtime.Ian Lance Taylor1-0/+26
This upgrades all of libgo other than the runtime package to the Go 1.4 release. In Go 1.4 much of the runtime was rewritten into Go. Merging that code will take more time and will not change the API, so I'm putting it off for now. There are a few runtime changes anyhow, to accomodate other packages that rely on minor modifications to the runtime support. The compiler changes slightly to add a one-bit flag to each type descriptor kind that is stored directly in an interface, which for gccgo is currently only pointer types. Another one-bit flag (gcprog) is reserved because it is used by the gc compiler, but gccgo does not currently use it. There is another error check in the compiler since I ran across it during testing. gotools/: * Makefile.am (go_cmd_go_files): Sort entries. Add generate.go. * Makefile.in: Rebuild. From-SVN: r219627
