Changes since v1:
- Replaced fragile checks on constants with check for literal pool
using "ldr r[0-9]+, \.L[0-9]+".
Ok for trunk?
--
With the changes in r15-1579-g792f97b44ff, the constants have been
updated.
This patch drops the fragile check on the constants and instead only
checks that there is no literal pool generated.
gcc/testsuite/ChangeLog:
* gcc.target/arm/pure-code/no-literal-pool-m0.c: Only check for
literal pools.
