Cherry Mui 0b72631a82 cmd/compile: generate args_stackmap for ABI0 assembly func regardless of linkname 
Currently, the compiler generates the argument stack map based on
the function signature for bodyless function declarations, if it
is not linknamed. The assumption is that linknamed function is
provided by (Go code in) another package, so its args stack map
will be generated when compiling that package.

Now we have linknames added to declarations of assembly functions,
to signal that this function is accessed externally. Examples
include runtime.morestack_noctxt, math/big.addVV. In the current
implementation the compiler does not generate its args stack map.
That causes the assembly function's args stack map missing.
Instead, change it to generate the stack map if it is a
declaration of an ABI0 function, which can only be defined in
assembly and passed to the compiler through the -symabis flag. The
stack map generation currently only works with ABI0 layout anyway,
so we don't need to handle ABIInternal assembly functions.

README.md

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.

To run just these tests, execute:

../bin/go test cmd/internal/testdir

To run just tests from specified files in this directory, execute:

../bin/go test cmd/internal/testdir -run='Test/(file1.go|file2.go|...)'

Standard library tests should be written as regular Go tests in the appropriate package.

The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:

  • it is most naturally expressed using the test runner; or
  • it is also applicable to gccgo and other Go tool chains.
