2018-10-25compiler: improve name mangling for packpathsIan Lance Taylor1-1/+1
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

2017-06-22runtime: make NumGoroutine wait for system goroutines to registerIan Lance Taylor1-0/+1
In libgo system goroutines register themselves after they start. That means that there is a small race between the goroutine being seen by the scheduler and the scheduler knowing that the goroutine is a system goroutine. That in turn means that runtime.NumGoroutines can overestimate the number of goroutines at times. This patch fixes the overestimate by counting the number of system goroutines waiting to start, and pausing NumGoroutines until those goroutines have all registered. This is kind of a lot of mechanism for this not very important problem, but I couldn't think of a better approach. The test for this is TestNumGoroutine in runtime/proc_test.go. The test is not currently run, but it will be soon. Reviewed-on: https://go-review.googlesource.com/46457 From-SVN: r249565
2017-05-11runtime: fix isSystemGoroutine for gccgoIan Lance Taylor1-0/+2
The gc toolchain decides whether a goroutine is a system goroutine by comparing startpc to a list of saved special PCs. In gccgo that approach does not work as startpc is often a thunk that invokes the real function with arguments, so the thunk address never matches the saved special PCs. This patch fixes gccgo's understanding of system goroutines. Since there are only a limited number of them, we simply change each one to mark itself as special. This fixes stack dumps and functions like runtime.NumGoroutine to behave more like gc. It also fixes the goprint test in the gc testsuite.

Fix handling of function values for -fgo-c-header to generate FuncVal*, not simply FuncVal. While we're here change runtime.nanotime to use clock_gettime with CLOCK_MONOTONIC, rather than gettimeofday. This is what the gc library does. It provides nanosecond precision and a monotonic clock.

2015-01-15libgo, compiler: Upgrade libgo to Go 1.4, except for runtime.Ian Lance Taylor1-0/+289
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
