--- Comment #16 from Christophe Lyon <clyon at gcc dot gnu.org> ---
That's what I did... (use -fdump-tree-cdce-details).
The assembler code is:
.arm
.fpu softvfp
.type foo, %function
foo:
@ args = 0, pretend = 0, frame = 0
@ frame_needed = 0, uses_anonymous_args = 0
@ link register save eliminated.
b sqrtf
which is a tail call ('b' is a jump instruction on arm, not a call).
