[Bug c/28508] New: Assembler Error: operand out of ragne (145 not between -128 and 127) form m32r-target

[inaoka dot kazuhiro at renesas dot com]

e have often gotten the following assembler error with -g option
since m32r-linux-gnu-gcc-4.0 released.

/tmp/cch1oLgA.s: Assembler messages:
/tmp/cch1oLgA.s:2591: Error: operand out of range (145 not between -128 and
127)/tmp/cch1oLgA.s:3358: Error: operand out of range (145 not between -128 and
127)/tmp/cch1oLgA.s:5195: Error: operand out of range (-130 not between -128
and 127)

We have been using DWARF2 since gcc-4.0.
It creates many local label symbols and makes pnop codes for code aligments.
We have no idia to avoid this error on compiling.

So we propose to change the range for using short bransh format code.

test case

bc.s and bnc.s have the range (form -512 to 508) of PC-relative.

If all 2byte instruction have alignment code (pnop)of debug information,
we must use 254/508.
But it's rare case.

FAIL Sample>
m32r-linux-gnu-gcc -S -g -O2 -o line_test.s.ng line_test.c
/tmp/ccHkZoqt.s: Assembler messages:
/tmp/ccHkZoqt.s:22: Error: operand out of range (198 not between -128 and 127)

PASS Sample> without -g option
m32r-linux-gnu-gcc -S -O2 -o line_test.s line_test.c

Kazu,

  I will apply your proposed patch.  

  One day we must really spend the time to fixup gcc so that the backends know
about these debug labels and their effect on code placement.

Cheers
  Nick

So the assembler adds the nops.  Hmm, is there a reason why GCC could add them
instead?

Could you please apply the same path to 4.1 and 4.0 branch?

Nick, are you going to backport this patch?

please mark it as closed, if it is not a candidate for a backport.
