This patch adds a support for OUTPUT_FORMAT linker script directive. Since I'm not 100% confident with BFD names you can use in the directive for all architectures, I added only a few in this patch. We can add other names for other archtiectures later. We still do not support triple-style OUTPUT_FORMAT directive, namely, OUTPUT_FORMAT(bfdname, big, little). If you pass -EL (little endian) or -EB (big endian) to the linker, GNU linkers pick up big or little as a BFD name, correspondingly, so that you can use a single linker script for bi-endian processor. I'm not sure if we really need to support that, so I'll leave it alone for now. Note that -m takes precedence over OUTPUT_FORAMT, but we always parse a BFD name given to OUTPUT_FORMAT for error checking. You cannot write an invalid name in the OUTPUT_FORMAT directive.

## Different "echo" commands on Windows interpret quoted strings and
|
|
## wildcards in similar but different way (On Windows, ARGV tokenization
|
|
## and wildcard expansion are not done by the shell but by each command.)
|
|
## Because of that reason, this test fails on some Windows environment.
|
|
## We can't write quoted strings that are interpreted the same way
|
|
## by all echo commands. So, we don't want to run this on Windows.

# RUN: mkdir -p %t.dir

## Note that we are using "cannot open no-such-file: " as a marker that the
|
|
## linker keep going when it found an error. That specific error message is not
|
|
## related to the linker script tests.
