@ This test has a partner (ldr-pseudo-darwin.s) that contains matching
|
|
@ tests for the ldr-pseudo on darwin targets. We need separate files
|
|
@ because the syntax for switching sections and temporary labels differs
|
|
@ between darwin and linux. Any tests added here should have a matching
|
|
@ test added there.
