The C version of the compiler had just one hash table, indexed by a (name string, pkg *Pkg) pair. Because we always know the pkg during a lookup, replace the one table with a per-Pkg map[string]*Sym. This also lets us do non-allocating []byte key lookups. This CL *does* change the generated object files. In the old code, export data and init calls were emitted in "hash table order". Now they are emitted in the order in which they were added to the table. Change-Id: I5a48d5c9add996dc43ad04a905641d901522de0b Reviewed-on: https://go-review.googlesource.com/6600Reviewed-by:

Strlit was just a poor excuse for a Go string. Use a Go string. In the one case where it was a string-or-nil (Type.Note), use a *string. Zconv was a poor excuse for %q. Use %q. The only important part about Zconv's implementation was that the compiler and linker agreed on the quoting rules. Now they both use %q instead of having two Zconvs. This CL *does* change the generated object files, because the quoted strings end up in symbol names. For example the string "\r\n" used to be named go.string."\r\n" and is now go.string."\x0d\n".

Aconv is the pretty-printer for instruction opcodes like AMOVQ. There was one for each architecture. Make the space of A names have a different region for each architecture, much as we did for the registers, so a single global Aconv function can do the work. Each architecture registers its region as a slice of names at a given offset. The global names like CALL and JMP are now defined only once. The A values are used for indexing tables, so make it easy to do the indexing by making the offset maskable. Remove a bunch of now-duplicated architecture-specific code.

PIE binaries can be built by the Go compiler in external link mode with extldflags="-pie". These binaries support ASLR (address space layout randomization) when executed on systems with appropriate kernel/dynamic linker support. This CL enables some cgo tests to run with -pie as a sanity check (in addition to the other linker flag combinations they already test). I have tested this functionality more thoroughly by building the full compiler testsuite (test/...) and standard library tests with -pie and executing them remotely on ChromeOS devices for all three linux architectures (linux_amd64, linux_386, and linux_arm).

This script is getting very close to complete, and is complex enough that I'd like to get what's there so far reviewed. With it the builder is left failing on eight packages. Two of those involve correcting GOROOT which may need modifications to this script, the others are either a unix sockets bug I have to hunt down or are caused by lldb getting stuck on SIGSEGV, a TODO.

Run rsc.io/grind rev a26569f on C->Go conversions. The new change in grind is the inlining of goto targets. If code says 'goto x' and the block starting at label x is unreachable except through that goto and the code can be moved to where the goto is without changing the meaning of its variable names, grind does that move. Simlarly, a goto to a plain return statement turns into that return statement (even if there are other paths to the return statement). Combined, these remove many long-distance gotos, which in turn makes it possible to reduce the scope of more variable declarations. (Because gotos can't jump across declarations, the gotos were keeping the declarations from moving.) Checked bit-for-bit compatibility with toolstash + buildall. Reduces compiler runtime in html/template by about 12%. Change-Id: Id727c0bd7763a61aa22f3daa00aeb8fccbc057a3 Reviewed-on: https://go-review.googlesource.com/6472Reviewed-by:

OpenBSD's sigprocmask system call passes the signal mask by value rather than reference, so vars are unnecessary. Additionally, declaring "var sigset_all = ^sigset_none" means sigset_all won't be initialized until runtime_init is called, but the first call to newosproc happens before then. I've witnessed Go processes on OpenBSD crash from receiving SIGWINCH on the newly created OS thread before it finished initializing.
