2020-11-20compiler, libgo: change mangling schemeIan Lance Taylor1-5/+5
Overhaul the mangling scheme to avoid ambiguities if the package path contains a dot. Instead of using dot both to separate components and to mangle characters, use dot only to separate components and use underscore to mangle characters.

2018-10-25compiler: improve name mangling for packpathsIan Lance Taylor1-6/+6
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

2018-09-25internal/bytealg, internal/cpu, internal/poll: portability fixesIan Lance Taylor1-1/+1
In internal/bytealg correct a +build tag to never build indexbyte_generic.go for the gofrontend, where we always use indexbyte_native.go. For internal/cpu let the Makefile define CacheLineSize using goarch.sh, rather than trying to enumerate all the possibilities in cpu_ARCH.go files. In internal/poll call the C fcntl function rather than using SYS_FCNTL. Change mksysinfo.sh to ensure that F_GETPIPE_SZ is always defined, and check that in internal/poll.
