Re: middle-end/8403: [sh-elf] ICE in gcc/testsuite/gcc.c-torture/execute/2001

["Naveen Sharma, Noida" <naveens at noida dot hcltech dot com>]

Hi,

Joern Rennecke suggested the following fix  for this problem 
But it hasn't made its way into the mainline yet.

I have been using this for quite some time now
(running make check, stress 1.17 and lot of other c code).
So it should be tested for sh-elf port throughly enough.

Since Joern wrote the fix, I would request him to generate
the changelog entry.

Thanks !!

Best Regards,
  Naveen Sharma.
