Manlio Perillo 805b4d5636 cmd/dist: wait for exit in bgwait after a fatal error
Currently, when a command scheduled by bgrun fails, bgwait returns to
the caller even in case the fatal error was detected.

In case of a syntax error in one of the standard packages, as an
example, the runInstall function will try to read the generated archive
file, only to fail since the file does not exist.  Since the runInstall
function is called in a goroutine, cmd/dist will continue to report
errors until all background goroutines are done.

Update the bgwait function to wait until program termination in case of
a fatal error, since returning to the caller (with an error, as an
example) will cause cmd/dist to report an additional error during the
next build phase.

Fixes #45410

David Chase a0963164e8 cmd/compile: add line number test for #49436
This enhances the existing line number test
to allow a specific -gcflags (e.g., -G=3)
and to permit ignoring duplicate line numbers
(which is arguably a bug, but not THIS bug,
and it lowers the risk of a flaky test).

Limited to Linux/Darwin and amd64/arm64,
also tests with "unified" mangling.

And, using these new powers, adds a test.

Updates #49436.

Russ Cox 36dbf7f7e6 cmd/go: add //go:embed all:pattern
When //go:embed d matches directory d, it embeds the directory
tree rooted at d, but it excludes files beginning with . and _,
as well as files having problematic names that will not be packaged
into modules (names such as .git and com1).

After long discussions on #42328 and #43854, we decided to keep
the behavior of excluding . and _ files by default, but to allow the pattern
prefix 'all:' to override this default. This CL implements that change.

Note that paths like .git and com1 are still excluded, as they must be,
since they will never be packed into a module.

Fixes #43854.

Michael Matloob 0e39946e8d cmd/go: add workspace pruning mode
This change corrects a bug in the handling of module loading of
workspaces. Namely, there is an assumption by the module pruning code
that if a root module is selected then the packages of that module can
be resolved without loading the whole module graph. This is not true
in workspace mode because two workspace modules can require different
versions of a dependency. Worse, one workspace module can directly
require a depencency that is transitively required by another
workspace module, changing the version of that module loaded in the
fully expanded graph.

To correct this, a new 'workspace' pruning mode is added where the
roots are the workspace modules themselves, satisfying the assumption
made by the module pruning logic.

The rest of this change accounts for the new pruning mode where it's
used and correctly sets the requirements in this pruning mode.

Filippo Valsorda 93bab8a2f9 crypto/elliptic: port P-224 and P-384 to fiat-crypto
Also, adopt addchain code generation for field inversion, and switch
P-521 to Montgomery multiplication, which is significantly slower but
allows us to reuse the P-224/P-256/P-384 wrapper code. No one uses P-521
anyway, and it's still faster than it was in Go 1.16.

Removed a portion of tests that ran the P-224 vectors against P-256,
for some reason.

Sadly, fiat-crypto is not fast enough to replace the generic 32-bit
P-256 implementation (just yet?).

A change in visible behavior is that we literally can't internally
operate on invalid curve points anymore (yay!) but the crypto/elliptic
API locked us into accepting any pair of integers for
Add/Double/ScalarMult and return no error (sigh), although of course
that's undefined behavior. Panics are always regretted. Returning nil
leads to panics. A fixed point might be exploited. The most reasonable
solution felt to return a made up random point, which is not that

Matthew Dempsky 6fefb7f9f3 cmd/compile: gracefully fallback when inline bodies are missing
Currently, we rely on a "crawling" step during export to identify
function and method bodies that need to be exported or re-exported so
we can trim out unnecessary ones and reduce build artifact sizes. To
catch cases where we expect a function to be inlinable but we failed
to export its body, we made this condition a fatal compiler error.

However, with generics, it's much harder to perfectly identify all
function bodies that need to be exported; and several attempts at
tweaking the algorithm have resulted in still having failure cases.
So for now, this CL changes a missing inline body into a graceful
failure instead.

This moves and slightly generalizes the -d debug flag parser from
cmd/compile/internal/base to cmd/internal/objabi so that we can use
the same debug flag syntax in other tools.

This makes a few minor tweaks to implementation details. The flag
itself is now just a flag.Value that gets constructed explicitly,
rather than at init time, and we've cleaned up the implementation a
little (e.g., using a map instead of a linear search of a slice). The
help text is now automatically alphabetized. Rather than describing
the values of some flags in the help text footer, we simply include it
in the flags' help text and make sure multi-line help text renders
sensibly.

In modules that specify 'go 1.17' or higher, the go.mod file
explicitly requires modules for all packages transitively imported by
the main module. Users tend to use 'go mod download' to prepare for
testing the main module itself, so we should only download those
relevant modules.

In 'go 1.16' and earlier modules, we continue to download all modules
in the module graph (because we cannot in general tell which ones are
relevant without loading the full package import graph).

'go mod download all' continues to download every module in
'go list all', as it did before.

Cherry Mui 988efd5819 cmd/link: don't use label symbol for absolute address relocations on ARM64 PE
On ARM64 PE, when external linking, the PE relocation does not
have an explicit addend, and instead has the addend encoded in
the instruction or data. An instruction (e.g. ADRP, ADD) has
limited width for the addend, so when the addend is large we use
a label symbol, which points to the middle of the original target
symbol, and a smaller addend. But for an absolute address
relocation in the data section, we have the full width to encode
the addend and we should not use the label symbol. Also, since we
do not adjust the addend in the data, using the label symbol will
actually make it point to the wrong address. E.g for an R_ADDR
relocation targeting x+0x123456, we should emit 0x123456 in the
data with an IMAGE_REL_ARM64_ADDR64 relocation pointing to x,
whereas the current code emits  0x123456 in the data with an
IMAGE_REL_ARM64_ADDR64 relocation pointing to the label symbol
x+1MB, so it will actually be resolved to x+0x223456. This CL
fixes this.

Don't inline a function fn that has no shape parameters, but is passed
at least one shape arg. This means we must be inlining a non-generic
function fn that was passed into a generic function, and can be called
with a shape arg because it matches an appropriate type parameter. But
fn may include an interface conversion (that may be applied to a shape
arg) that was not apparent when we first created the instantiation of
the generic function. We can't handle this if we actually do the
inlining, since we want to know all interface conversions immediately
after stenciling.  So, we avoid inlining in this case.
