2018-10-25compiler: improve name mangling for packpathsIan Lance Taylor7-76/+153
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).

2018-10-18compiler: list indirect imports separately in export dataIan Lance Taylor7-23/+255
Previously when export data referred to a type that was not defined in a directly imported package, we would write the package name as additional information in the type's export data. That approach required all type information to be read in order. This patch changes the compiler to find all references to indirectly imported packages, and write them out as an indirectimport line in the import data. This will permit us to read exported type data out of order. The type traversal used to find indirect imports is a little more complicated than necessary in preparation for later patches in this series.

In 1.11 writebarrierptr is going away, so change the compiler to call gcWriteBarrier instead. We weren't using gcWriteBarrier before; adjust the implementation to use the putFast method.

In that case the m will generally have a p, but systemstack may be called by wbBufFlush as part of flushing the write barrier buffer. At that point the buffer is full, so we can not do a write barrier. So adjust the existing code in kickoff so that in the case where we are g0, don't do any write barrier at all.

2018-09-13runtime: avoid write barriers with traceback infoIan Lance Taylor1-1/+1
Unlike the gc runtime, libgo stores traceback information in location structs, which contain strings. Therefore, copying location structs around appears to require write barriers, although in fact write barriers are never important because the strings are never allocated in Go memory. They come from libbacktrace. Some of the generated write barriers come at times when write barriers are not permitted. For example, exitsyscall, marked nowritebarrierrec, calls exitsyscallfast which calls traceGoSysExit which calls traceEvent which calls traceStackID which calls trace.stackTab.put which copies location values into memory allocated by tab.newStack. This write barrier can be invoked when there is no p, causing a crash. This change fixes the problem by ensuring that location values are copied around in the tracing code with no write barriers. This was found by fixing the compiler to fully implement //go:nowritebarrierrec; CL to follow. Reviewed-on: https://go-review.googlesource.com/134226 From-SVN: r264282

When the slice has enough capacity the pointer is not changing and no write barrier is required. These changes are required to avoid write barriers in the method randomOrder.reset in the runtime package. That method is called from procresize, at a point where we do not want to allocate memory.

2018-08-24runtime: remove the dummy arg of getcallerspIan Lance Taylor2-6/+2
This is a port of https://golang.org/cl/109596 to the gofrontend, in preparation for updating libgo to 1.11. Original CL description: getcallersp is intrinsified, and so the dummy arg is no longer needed. Remove it, as well as a few dummy args that are solely to feed getcallersp. Reviewed-on: https://go-review.googlesource.com/131116 From-SVN: r263840
