Hmm, dropping the stmt looks like it would be a "hack". Alex - if I just set
flag_var_tracking_assignments to 1 if I encounter a GIMPLE_DEBUG during read-in
I get
t.c: In function 'foo':
t.c:1:6: error: unrecognizable insn:
(debug_insn 6 5 14 t.c:3 (var_location:SI hex (mem/c/i:SI (plus:SI (reg/f:SI 20
frame)
(const_int -4 [0xfffffffc])) [0 hex+0 S4 A32])) -1 (nil))
t.c:1:6: internal compiler error: in insn_default_length, at
config/i386/i386.md:544
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
is there sth else that I need to do to "enable" VTA?
