Hi Andrew. I uploaded the wrong preprocessed source to the GCC
bugzilla entry. It included the __attribute__((noinline)) workaround
which hides the problem.
I've fixed that and re-attached the correct version. The assembly
version contains the following:
.size wm8974_pcm_hw_params, .-wm8974_pcm_hw_params
.global __aeabi_uidiv
.global __aeabi_uidivmod
.global __aeabi_uldivmod
.align 2
.thumb
.thumb_func
.type wm8974_set_dai_pll, %function
wm8974_set_dai_pll:
@ args = 4, pretend = 0, frame = 0
@ frame_needed = 0, uses_anonymous_args = 0
push {r3, r4, r5, r6, r7, r8, r9, lr}
...
