1 @ This test has a partner (ldr-pseudo.s) that contains matching 2 @ tests for the ldr-pseudo on linux targets. We need separate files 3 @ because the syntax for switching sections and temporary labels differs 4 @ between darwin and linux. Any tests added here should have a matching 5 @ test added there. 6 7 @RUN: llvm-mc -triple armv7-apple-darwin %s | FileCheck %s 8 @RUN: llvm-mc -triple thumbv5-apple-darwin %s | FileCheck %s 9 @RUN:
