Summary:
Separate the evaluation of expressions from printing
of results. This is in preparation for splitting the
core of the interpreter out for use in alternative
interpreter frontends.
At the same time, the output is made less noisy in
response to comments on the golang-nuts announcement.
We would ideally print out values using Go syntax,
but this is impractical until we have libgo based on
Go 1.5. When that happens, fmt's %#v will handle
reflect.Value better, and so we can fix/filter type
names to remove automatically generated package names.

The check-libgo target runs "make check" in the
libgo package, which can take a long time on
slower machines. To prevent buildbot failures
due to timeout, we can use Ninja's console pool

Patch by Michal Cierniak!
This patch increments the "Debug Info Version" from 2 to 3.
This is a nop if you just want to generate binaries. I verified
that with and without this patch, when I run llgo -g on a Go
source file, I get exactly the same binary. The purpose of the
patch is to make it possible to run the llvm-dis tool. Without
the patch, it is impossible to disassemble files generated with
llgo:
$ llgo -c -g -emit-llvm src/hello.go
$ llvm-dis hello.o
llvm-dis: warning: ignoring debug info with an invalid version (2) in hello.o

Switch gofrontend to using go.googlesource.com, and
update to 81eb6a3f425b2158c67ee32c0cc973a72ce9d6be.
There are various changes required to update to the
go 1.5 runtime:
typemap.go is changed to accommodate the change in representation for equal/hash algorithms, and the removal of the zero value/type.
CMakeLists.txt is updated to add the build tree to the package search path, so internal packages, which are not installed, are found.
various files changes due to removal of __go_new_nopointers; the same change as in D11863, but with NoUnwindAttribute added to the added runtime functions which are called with "callOnly".
minor cleanups in ssa.go while investigating issues with unwinding/panic handling.

Summary:
Another attempt at resolving the runtime assertion
in llgoi due to data layout mismatch between module

The X86 data layout constant appears to be unnecessary,
and does not match what the execution engine picks.
Using the registered Target, we pick the same data
layout as the execution engine.
While I was in the vicinity, I deleted the last
remnants of PNaCl support.

As llgoi is installed, it must be built or the install
target will fail; there is no implicit dependency.
Adding llgoi to "ALL" makes building llgo as part of an

This takes us to Go 1.4. Also includes a couple of changes to the test
suite, both in the runtime package:
- Disable TestSetPanicOnFault. We cannot support this scenario at all,
due to LLVM's lack of non-call exceptions.
- Tweak TestFinalizerType. This test only passes with two GC runs.

go/loader creates a fresh package map for each source package it imports. In
llgoi this caused binary imported packages to be imported anew for every input
line, resulting in spurious type errors and panics in go/ssa when encountering
previously imported types. Fix this by setting types.Config.Packages to our
internal package map.

At the same time, perform a number of simplifications:

Summary:
With this patch, llgo uses ssautil.Switches
to reconstitute (and synthesise) switches,
which can then be lowered to lookup tables,
trees, etc.
We currently only handle integer const case
switches. We erase the comparison blocks (other
than the initial block), and generate a switch
instruction at the end of the block starting
the if-else-if chain. ssautil.Switches does
not remove duplicate const cases (e.g. same
operands for "||"), so we do this in llgo for
now.

The new ABI is simpler for use cases such as dynamically loaded packages.
The calling convention for import functions is similar to what go/ssa would
produce if BareInits were cleared. However, simply clearing this flag causes
two additional issues:
1) We would need to special case the 'init$guard' variable (see
discussion in https://codereview.appspot.com/78780043/).
2) The call to __go_register_gc_roots needs to appear in the right
place, i.e. after the guard check. Making this check appear
in the right place with non-bare inits seems unreliable at best.
So we keep BareInits set and generate the necessary code manually.
It is still possible to get the old ABI by specifying a path to a gccgo
installation.

multilib build and installs.
Summary:
This requires introducing a generated header to encapsulate the
LLVM_LIBDIR_SUFFIX value from the build system and push it into the go
code. From there, I've adjusted the gllgo code to systematically use
this rather than a raw "lib". This requires some awkwardness as one of
the flags *must* be "lib"-relative for compatibility with how gccgo
works. For that flag, we use ".." to back up a directory and then go
into the proper lib directory.
