Dear list member,
I am facing a problem in using avr-gcc with atmega32 or even atmega128.

The size of my executable (using gcc) is 31KB. But, I am doing image
processing which requires five 2-dimensional image arrays of size
image_height  by image_width.

Even though I keep the size of my image quite less i.e. 15 * 17 pixels
(778 bytes), then also I am getting an internal compiler error and it is
asking me to report the bug at gcc.gnu.org.

The error is as follows:
hyst.c:161: error: unrecognizable insn:
(insn 218 1016 1119 30 0x40079814 (set (reg:HI 114)
        (const_int 32800 [0x8020])) -1 (nil)
hyst.c:161: internal compiler error: in extract_insn, at recog.c:2175
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

When I used image of size 141*106, I got 2 such errors.

Could you please reply to address@hidden if you have a solution
or suggestion.

Thanking you,

Yours sincerely,
Shubham Jain
