[-- Attachment #1: Type: text/plain, Size: 3723 bytes --]
Step 3: Test cases to verify the code size reduction.
gcc/gcc/testsuite/ChangeLog:
2014-08-21 Tony Wang <tony.wang@arm.com>
* gcc.target/arm/size-optimization-ieee-1.c: New test case
* gcc.target/arm/size-optimization-ieee-2.c: New test case
* lib/gcc-dg.exp: Add new function scan-symbol-common, scan-symbol-yes,
scan-symbol-no to scan a user defined symbol in final elf file
BR,
Tony
