2018-10-25compiler: improve name mangling for packpathsIan Lance Taylor1-2/+2
The current implementation of Gogo::pkgpath_for_symbol was written in a way that allowed two distinct package paths to map to the same symbol, which could cause collisions at link- time or compile-time. Switch to a better mangling scheme to insure that we get a unique packagepath symbol for each package. In the new scheme instead of having separate mangling schemes for identifiers and package paths, the main identifier mangler ("go_encode_id") now handles mangling of both packagepath characters and identifier characters. The new mangling scheme is more intrusive: "foo/bar.Baz" is mangled as "foo..z2fbar.Baz" instead of "foo_bar.Baz". To mitigate this, this patch also adds a demangling capability so that function names returned from runtime.CallersFrames are converted back to their original unmangled form. Changing the pkgpath_for_symbol scheme requires updating a number of //go:linkname directives and C "__asm__" directives to match the new scheme, as well as updating the 'gotest' driver (which makes assumptions about the correct mapping from pkgpath symbol to package name). Fixes golang/go#27534. Reviewed-on: https://go-review.googlesource.com/c/135455 From-SVN: r265510

2017-01-14libgo: update to Go 1.8 release candidate 1Ian Lance Taylor2-12/+15
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.

2016-10-17runtime: copy rdebug code from Go 1.7 runtimeIan Lance Taylor4-24/+62
While we're at it, update the runtime/debug package, and start running its testsuite by default. I'm not sure why runtime/debug was not previously updated to 1.7. Doing that led me to fix some minor aspects of runtime.Stack and the C function runtime/debug.readGCStats. Reviewed-on: https://go-review.googlesource.com/31251 From-SVN: r241261
