libgo: separate mksysinfo inputs into separate Makefile targets This is a step toward a version of mksysinfo that generates information for the runtime package.

libgo: handle linking to NetBSD's versioned symbols On NetBSD, for backwards compatibility, various libc symbols are renamed to a symbol with a version suffix. For example, this is the (abbreviated) definition of sigaction: int sigaction(...) __asm__ ("__sigaction14") This poses a challenge for libgo, which attempts to link sigaction by way of an "//extern" comment: //extern sigaction func sigaction(...) This results in a reference to the deprecated compatibility symbol "sigaction", rather than the desired "__sigaction14" symbol. This patch introduces a new "//extern-sysinfo" comment to handle this situation. The new mklinknames.awk script scans a package for these comments and outputs a "//go:linkname" directive that links the wrapper to the correct versioned symbol, as determined by parsing the __asm__ annotation on the function's declaration in gen-sysinfo.go. For now, only the following packages are scanned by mklinknames.awk: os os/user runtime syscall gotools/: * Makefile.am (check-runtime): Add runtime_linknames.go to --extrafiles. * Makefile.in: Regenerate.

libgo: adjust sysinfo scripts for changed -fdump-go-spec The -fdump-go-spec flag to GCC recently changed to be more fastidious about handling incomplete types. This caused some breakage in mk[r]sysinfo.sh on Solaris. This commit adjusts for the new behavior. Specifically: * Types that refer to _in6_addr may be hidden behind a typedef and can no longer be filtered out with `grep -v in6_addr`. Instead just rewrite the definition of _in6_addr to [16]byte wherever it appears. * timestruc_t is now (correctly) emitted as an alias for timespec, so this case is handled specially. * stdio.h is included in sysinfo.c to avoid emitting an incomplete definition of the FILE type. * Dummy definitions for _u?pad128_t are now emitted automatically, which conflict with the definitions installed by mk[r]sysinfo.sh. These definitions were actually dead code, so just remove them. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/278672

libgo, syscall: fix ptrace implementation on MIPS On MIPS, the correct structure for PtraceRegs is 'struct pt_regs' which is declared in linux/ptrace.h. Previously no PtraceRegs structure was created on MIPS because 'struct user_regs_struct' doesn't exist there. Fallback to using pt_regs when the PtraceRegs structure is generated in mksysinfo.sh, then adjust syscall_linux_mipsx.go to read the program counter from the correct field. In addition, implement PtraceGetRegs and PtraceSetRegs on all 3 ABI variants. syscall_linux_mips64x.go can now be removed since the ptrace code on all 3 ABIs is identical.

runtime: copy internal locking code from Go 1.7 runtime Remove the old locking code written in C. Add a shell script mkrsysinfo.sh to generate the runtime_sysinfo.go file, so that we can get Go copies of the system time structures and other types. Tweak the compiler so that when compiling the runtime package the address operator does not cause local variables to escape. When the gc compiler compiles the runtime, an escaping local variable is treated as an error. We should implement that, instead of this change, when escape analysis is turned on. Tweak the compiler so that the generated C header does not include names that start with an underscore followed by a non-upper-case letter, except for the special cases of _defer and _panic. Otherwise we translate C types to Go in runtime_sysinfo.go and then generate those Go types back as C types in runtime.inc, which is useless and painful for the C code. Change entersyscall and friends to take a dummy argument, as the gc versions do, to simplify calls from the shared code. Reviewed-on: https://go-review.googlesource.com/30079 From-SVN: r240657

libgo: add type/const references to sysinfo.c This patch adds explicit references to various types and constants defined by the header files included by sysinfo.c (used to drive the generation of gen-sysinfo.go as part of the libgo build via the GCC "-fdump-go-spec" option). The intent is to enable clients to gather the same info generated by "-fdump-go-spec" by instead reading the generated DWARF from a sysinfo.o object file compiled with "-g". Some compilers (notably clang) try to omit DWARF records for a given type unless there is an explicit use of it in the translation unit; the additional references are to insure that everything we want to see in the DWARF shows up.

libgo: support gollvm build on arm64 linux This CL serves as part of an initial change for enabling gollvm building on arm64 linux, the rest of the change will be covered by another one to the gollvm repo. Incorporate type definition of 'uint128' to 'runtime' and 'syscall' packges, the change is not specific to arm64 linux but made available for all platforms. Verified by building and unit-testing gollvm on linux x86-64 and arm64. Verified by building and checking gccgo on linux x86-64 and arm64.
