This patch updates issue10441.go to the upstream version. The test
only needs to be compiled, not linked. Linking failed on some

This Go frontend patch by Cherry Mui makes the escape analysis pass
stricter about builtin functions In the places where we handle
builtin functions, list all supported ones, and fail if an unexpected
one is seen. So if a new builtin function is added in the future we
can detect it, instead of
This Go frontend patch by Cherry Mui supports the new language
constructs in escape analysis. Previous patches added new language
constructs in Go 1.17, specifically, unsafe.Add, unsafe.Slice, and
conversion from a slice to a pointer
to an array. This patch handles them in the escape analysis.
This patch to the Go frontend and libgo changes selectnbrecv to return
two values. The only difference between selectnbrecv and
selectnbrecv2 is that the latter uses a pointer argument as the second
return value from chanrecv. This patch changes selectnbrecv to return
the two values from

The upcoming Go 1.17 release has a new language feature: it permits
conversions from slice types to pointer-to-array types. If the slice
is too short, the conversion panics. This patch implements this new
feature in gccgo. Bootstrapped and ran Go testsuite on

The upcoming Go 1.17 release adds two new functions to the unsafe
package: unsafe.Add and unsafe.Slice. These functions must be
implemented in the compiler. This patch implements them for gccgo.
Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu. Committed
to mainline.

This patch changes the Go frontend to avoid aliases in receiver types.
If a package declares a method on an alias type, the alias would be
used in the export data. This would then trigger a compiler assertion
on import: we should not be adding methods to aliases.
Fix the problem by ensuring that

This patch to the Go frontend sets DECL_NAMELESS for temporary
variables. This is consistent with what create_tmp_var does, but is
used for cases where we can't use create_tmp_var. Bootstrapped and
ran Go testsuite on x86_64-pc-linux-gnu. Committed to mainline.

This patch to the Go frontend reduces the number of temporaries that
the compiler genrrates for composite literals. For a composite
literal we only need to introduce a temporary variable if we may be
converting to an interface type, so only do it then. This saves over
80% of compilation time
