ad8b7a70c5 test: fix fixedbugs/issue30908.go to work with no-opt builder
Update the issue 30908 test to work with the no-opt builder
(this requires a corresponding change in the linker as well).
As part of this change, 'rundir' tests are now linked without
passing "-w" to the linker.

Updates #30908.
Fixes #31034.

cacab64555 cmd/link: change -strictdups checking to handle mix of flags
Update the recently-added '-strictdups' sanity checking to avoid
failing the link in cases where we have objects feeding into the link
with a mix of command line flags (and in particular some with "-N" and
some without). This scenario will trigger errors/warnings due to
inlinable functions and wrapper functions that have different sizes
due to presence or lack of optimization.

Update #31034.

d47db6dc0c cmd/compile: fix literal struct interface {} lost passing by value
CL 135377 introduces pass strings and slices to convT2{E,I} by value.
Before that CL, all types, except interface will be allocated temporary
address. The CL changes the logic that only constant and type which
needs address (determine by convFuncName) will be allocated.

It fails to cover the case where type is static composite literal.
Adding condition to check that case fixes the issue.

Also, static composite literal node implies constant type, so consttype
checking can be removed.

Fixes #30956

On AIX, shared objects must be wrapped under an archive file.

For testso, creating libcgosotest with an extern symbol isn't
AIX-friendly. By default, ld will block such behavior. Rather than
forcing ld to work as on Linux and using the run-time linking,
goCallback became a function pointer which is set by setCallback().

It is hard (maybe impossible) to make WriteAt work portably.

f24e1099cb bytes: make TrimSpace return nil on all-space input
Issue #29122 introduced a subtle regression due to the way that
TrimFuncLeft is written: previously TrimSpace returned nil when given
an input of all whitespace, but with the #29122 changes it returned an
empty slice on all-space input.

This change adds a special case to the new, optimized TrimSpace to go
back to that behavior. While it is odd behavior and people shouldn't be
relying on these functions returning a nil slice in practice, it's not
worth the breakage of code that does.

This tweak doesn't change the TrimSpace benchmarks significantly.

f2e51f0015 crypto/x509: look for CAs at /etc/ssl/cert.pem for Alpine Linux
Alpine Linux uses /etc/ssl/cert.pem as default ca-bundle which
is preinstalled since 3.7 and was installed as part of the libressl
package in 3.5 and 3.6.

The path /etc/ssl/certs/ca-certificates.crt is only valid if the full
ca-certificates package is installed by hand, which contains all
single CA certs and uses update-ca-certificates to bundle them.

The priority for /etc/ssl/certs/ca-certificates.crt should be kept
higher than /etc/ssl/cert.pem in case the user installed custom
CA certs.

e007916cea cmd/go/internal/load: always use DefaultExecName to determine binary name
It should produce equivalent results to split on the import path of the
package rather than its directory, in GOPATH mode. That means the common
code in DefaultExecName can be used.

We're in the middle of Go 1.12 cycle, so now is a good time to make it
happen for Go 1.13.

Modify isVersionElement to accept path elements like "v2", "v3", "v10",
rather than "/v2", "/v3", "/v10". Then use it in DefaultExecName instead
of the ad-hoc isVersion function. There is no change in behavior.

Add tests for DefaultExecName and isVersionElement.

c4f87ed26f cmd/compile: fix "append outside assignment" ICE
Some special-case code paths in order.go didn't expect OCALLFUNC to
have Ninit; in particular, OAS2FUNC and ODEFER/OGO failed to call
o.init on their child OCALLFUNC node. This resulted in not all of the
AST being properly ordered.

This was noticed because order is responsible for introducing an
invariant around how OAPPEND is used, which is enforced by walk.
However, there were perhaps simpler cases (e.g., simple order of
evaluation) that were being silently miscompiled.

late in the build.

88adc33827 context: remove dependency on reflect
Make context depend on reflectlite instead of reflect in effort to
eventually make net no longer depend on unicode tables.

With this CL we're down to just:

    net -> context -> fmt -> unicode tables

The next CL can remove context -> fmt.

fbd74a8922 test: support -ldflags for "rundir" tests, new -P option
For "rundir" tests, allow users to add in linker flags as well as
compiler flags, e.g.

// rundir -m -ldflags -w

The directive above will pass "-m" to the compiler on each package compilation
and "-w" to the linker for the final link.

In addition, if "-P" is specified with 'rundir', then for each compile
pass in "-p <X>" to set the packagepath explicitly, which is closer to
how the compiler is run by 'go build'.

68a98d5279 cmd/compile: better handling for PAUTOHEAP in DWARF inline gen
When generating DWARF inline info records, the post-SSA code looks
through the original "pre-inline" dcl list for the function so as to
handle situations where formal params are promoted or optimized away.
This code was not properly handling the case where an output parameter
was promoted to the heap -- in this case the param node is converted
in place from class PPARAMOUT to class PAUTOHEAP. This caused
inconsistencies later on, since the variable entry in the abstract
subprogram DIE wound up as a local and not an output parameter.

Fixes #30908.
