2015-01-15libgo, compiler: Upgrade libgo to Go 1.4, except for runtime.Ian Lance Taylor13-99/+244
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

2014-06-04libgo: Merge from revision 18783:00cce3a34d7e of master library.Ian Lance Taylor2-1/+15
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

2012-10-26syscall: fix creds_test to reliably close os.FileIan Lance Taylor1-2/+6
Uncovered by Uros Bizjak. Before this patch the test would close the file descriptor but not the os.File. When the os.File was GC'ed, the finalizer would close the file descriptor again. That would cause problems if the same file descriptor were returned by a later call to open in another test.
