2016-11-10runtime: copy signal code from Go 1.7 runtimeIan Lance Taylor1-176/+0
Add a little shell script to auto-generate runtime.sigtable from the known signal names. Force the main package to always import the runtime package. Otherwise some runtime package global variables may never be initialized. Set the syscallsp and syscallpc fields of g when entering a syscall, so that the runtime package knows when a g is executing a syscall. Fix runtime.funcPC to avoid dead store elimination of the interface value when the function is inlined. Reviewed-on: https://go-review.googlesource.com/33025 From-SVN: r242060
2016-08-30runtime: use -fgo-c-header to build C header fileIan Lance Taylor1-8/+8
Use the new -fgo-c-header option to build a header file for the Go runtime code in libgo/go/runtime, and use the new header file in the C runtime code in libgo/runtime. This will ensure that the Go code and C code share the same data structures as we convert the runtime from C to Go. The new file libgo/go/runtime/runtime2.go is copied from the Go 1.7 release, and then edited to remove unnecessary data structures and modify others for use with libgo. The new file libgo/go/runtime/mcache.go is an initial version of the same files in the Go 1.7 release, and will be replaced by the Go 1.7 file when we convert to the new memory allocator. The new file libgo/go/runtime/type.go describes the gccgo version of the reflection data structures, and replaces the Go 1.7 runtime file which describes the gc version of those structures. Using the new header file means changing a number of struct fields to use Go naming conventions (that is, no underscores) and to rename constants to have a leading underscore so that they are not exported from the Go package. These names were updated in the C code. The C code was also changed to drop the thread-local variable m, as was done some time ago in the gc sources. Now the m field is always accessed using g->m, where g is the single remaining thread-local variable. This in turn required some adjustments to set g->m correctly in all cases. Also pass the new -fgo-compiling-runtime option when compiling the runtime package, although that option doesn't do anything yet.

2016-02-12runtime: For c-archive/c-shared, install signal handlers synchronously.Ian Lance Taylor1-1/+9
This is a port of https://golang.org/cl/18150 to the gccgo runtime. The previous behaviour of installing the signal handlers in a separate thread meant that Go initialization raced with non-Go initialization if the non-Go initialization also wanted to install signal handlers. Make installing signal handlers synchronous so that the process-wide behavior is predictable. Reviewed-on: https://go-review.googlesource.com/19494 From-SVN: r233393

2014-06-04libgo: Merge from revision 18783:00cce3a34d7e of master library.Ian Lance Taylor1-0/+9
This revision was committed January 7, 2014. The next revision deleted runtime/mfinal.c. That will be done in a subsequent merge. This merge changes type descriptors to add a zero field, pointing to a zero value for that type. This is implemented as a common variable. * go-gcc.cc (Gcc_backend::implicit_variable): Add is_common and alignment parameters. Permit init parameter to be NULL. From-SVN: r211249
