This change uses errorCheck and wantedErrors functions copied from
the test/run.go to eliminate use of the test/errchk perl script.
Tests' error messages that contained full filenames were changed to
have base filenames because the errorCheck function processes output

go build
command is short for
go build .
and it builds . package. When command above is executed from
directory inside of GOPATH, it uses GOPATH to calculate package
source directory. So . package uses GOPATH as part of package
source directory.
On the other hand
go build -ldflags=abc
only passes flag to the linker for packages that are listed
on the command line. The command above assumes . package again,
and that package source path is compared with current directory.
Current code compares result of os.Getwd with what GOPATH

in letter case on Windows. For example, one might return
c:\gopath\..., while the other might contain C:\GOPATH.

Fix a problem in DWARF inline debug generation relating to handling of
statically unreachable local variables. For a function such as:
const always = true
func HasDeadLocal() int {
if always {
return 9
}
x := new(Something)
...
return x.y
}
the variable "x" is placed onto the Dcl list for the function during
parsing, but the actual declaration node is deleted later on when
gc.Main invokes "deadcode". Later in the compile the DWARF code emits
an abstract function with "x" (since "x" was on the Dcl list at the
point of the inline), but the export data emitted does not contain
"x". This then creates clashing/inconsistant DWARF abstract function
DIEs later on if HasDeadLocal is inlined in somewhere else.
As a fix, the inliner now pruned away variables such as "x" when
creating a copy of the Dcl list as part of the inlining; this means
that both the export data generator and the DWARF emitter wind up
seeing a consistent picture.

When using gccgo/GoLLVM, there is no package file for a standard
library package. Since it is impossible for the go tool to rebuild the
package, and since the package file exists only in the form of a .gox
file, this seems like the best choice. Unfortunately it was confusing
vet, which wanted to see a real file. This caused vet to report errors
about missing package files for standard library packages. The
gccgoimporter knows how to correctly handle this case. Fix this by
1) telling vet which packages are standard;
2) letting vet skip those packages;
3) letting the gccgoimporter handle this case.
As a separate required fix, gccgo/GoLLVM has no runtime/cgo package,
so don't try to depend on it (as it happens, this fixes#25324).
The result is that the cmd/go vet tests pass when using -compiler=gccgo.

Embedded interfaces in interfaces must take the form of a (possibly
qualified) type name. Before alias types, a type name always denoted
a defined (formerly "named") type. The introduction of alias types
enabled embedding of non-defined types via alias type names, as in:
type T interface { E }
type E interface { m() }
Both cmd/compile and gccgo accept this kind of code, and the spec does
not prohibit it. There may be code in the wild that makes use of this.
go/types was written under the assumption that embedded interfaces
were always defined types; and that assumption was even reflected in
the go/types API.
This change removes this restriction in the implementation (which
happens to make it simpler), and in the API (by adding additional
functions and deprecating the corresponding older versions).
It also replaces uses of NewInterface and Embedded (old API) by
NewInterface2 and EmbeddedType (new API) in dependent packages
(importers).
The old API remains in place for backward compatibility and is marked
as deprecated.

Go's SSA instructions only operate on registers. For example, an add
instruction would read two registers, do the addition and then write
to a register. WebAssembly's instructions, on the other hand, operate
on the stack. The add instruction first pops two values from the stack,
does the addition, then pushes the result to the stack. To fulfill
Go's semantics, one needs to map Go's single add instruction to
4 WebAssembly instructions:
- Push the value of local variable A to the stack
- Push the value of local variable B to the stack
- Do addition
- Write value from stack to local variable C
Now consider that B was set to the constant 42 before the addition:
- Push constant 42 to the stack
- Write value from stack to local variable B
This works, but is inefficient. Instead, the stack is used directly
by inlining instructions if possible. With inlining it becomes:
- Push the value of local variable A to the stack (add)
- Push constant 42 to the stack (constant)
- Do addition (add)
- Write value from stack to local variable C (add)
Note that the two SSA instructions can not be generated sequentially
anymore, because their WebAssembly instructions are interleaved.

The upstream pprof implements the readline feature using

It would be ideal to use the same readline support package as

However, bringing in third-party packages requires more work

As a result, this change implements the similar feature
for the pprof command included in the go distribution

for now.
Auto-completion is not yet supported (same in the upstream).
The feature is enabled only in linux, windows, darwin, and

There is no NL at the end of README, and that make it strange
when doing "cat misc/android/README".

The splice syscall is buggy prior to linux 2.6.29. Instead of returning
0 when reading a closed socket, it returns EAGAIN. While it is possible
to detect this (HAProxy falls back to recv), it is simpiler to avoid
using splice all together. the "fcntl(fd, F_GETPIPE_SZ)" syscall is used
detect buggy versions of splice as the syscall returns EINVAL on
versions prior to 2.6.35.
Fixes#25486

In rare circumstances that we don't yet fully understand, the g
register can be spilled to the stack and then reloaded. If this
happens, liveness analysis sees a pointer load into a
non-general-purpose register and panics.
We should fix the root cause of this, but fix the build for now by
ignoring pointer loads into the g register.
For #25504.

There's semantically-but-not-literally equivalent code in
two cases for joining blocks' value lists in ssa/fuse.go.
It can be made literally equivalent, then commoned up.
Updates #25426.
