Each backend has slightly different paths on "debug information exists vs. debug information doesn't exist". Patch #1 changes gdb.perf/skip-prologue.exp so that we can compile the test case with and without debug information. Patch #2 and patch #3 improves arm and aarch respectively. *** BLURB HERE *** Yao Qi (3): Compile gdb.perf/skip-prologue.c with and without debug info Use code cache in arm prologue analyzer Use code cache in aarch64 prologue analyzer gdb/aarch64-tdep.c | 2 +- gdb/arm-tdep.c | 38 ++++++++++++++++---------------- gdb/testsuite/gdb.perf/skip-prologue.exp | 8 ++++++- 3 files changed, 27 insertions(+), 21 deletions(-) -- 1.9.1
