1. Yes, the flags used are -mthumb -Os -march=armv5te.
2. For completeness, I also tried to generate 32-bit instructions. In this case
of ARM mode, GCC 4.5.0 (trunk as of last week) didn't store things onto stack

1. Yes, the flags used are -mthumb -Os -march=armv5te.
4c: e8bd41f0pop {r4, r5, r6, r7, r8, lr}
50: e12fff1ebx lr
This looks more like a return

For completeness the options are with -mthumb -Os -march=armv5te ?
With trunk I see a size of 52 bytes and this code.
.type test, %function
test:
push{r4, r5, r6, r7, lr}
sub
