Test results: This is sufficient to get a build that can compile
trivial hello world programs. Nontrivial operations (like "go install")
crash in the runtime. However, GOGC=off completely avoids these crashes
and is able to compile more complex libraries, so likely a GC issue.
Support needs to be added to /x/sys/unix package for any real-world
programs to function.
The values in goarch.sh are taken from the recommendations in this
linux-parisc thread:
https://lore.kernel.org/linux-parisc/7013a3e7d6c9c77c5010bc1c72971758@matoro.tk/t/#u
Additionally it's suggested that the GC issues may be related to the
stack implementation in libgo/runtime/stack.c, because the stack grows
upwards on hppa.
ChangeLog:
* libgo/configure: Regenerate.
* libgo/configure.ac: Add hppa.
* libgo/go/cmd/cgo/main.go: Likewise.
* libgo/go/go/build/syslist.go: Likewise.
* libgo/go/runtime/hash32.go: Build for hppa.
* libgo/go/runtime/lfstack_32bit.go: Likewise.
* libgo/go/runtime/mpagealloc_32bit.go: Likewise.
* libgo/go/runtime/panic32.go: Likewise.
* libgo/go/syscall/endian_big.go: Likewise.
* libgo/goarch.sh: Provide definitions for hppa.
* libgo/match.sh: Add hppa.
* libgo/testsuite/gotest: Likewise.
* libgo/go/internal/syscall/unix/sysnum_linux_hppa.go: New file.
gcc/testsuite/ChangeLog:
* go.test/go-test.exp: Add hppa.
