Thanks for the patch, Martin. I checked that our code works again also

--- Comment #10 from Jürgen Reuter ---
I can confirm that re-introducing the line
case BUILT_IN_STRCPY_CHK:
in lines 619/20 in tree-ssa-strlen.c does indeed solve this problem and also
the problem (ICE) with our code reported in PR86103.

Ah I see, so when Martin Liska removed the MPX-support in r261304 you removed
too much from the tree-ssa-strlen.c file? Then a rather fast fix is hopefully
possible.

And this is the assembler code when executing -S -O1 (cf. below), while for the
-O2
version the compilation leads to an assembler file showing only the .text line:
.text
.globl _hoo
_hoo:

--- Comment #4 from Jürgen Reuter ---
This is the dump-tree-original file, which is produced despite of the ICE, and
which is identical for -O1 and -O2:
;; Function __sputc (null)
;; enabled by -tree-original
{
if ( --_p->_w >= 0 || _p->_w

--- Comment #3 from Jürgen Reuter ---
I can definitely confirm this problem. Works with -O0 and -O1. Fails with -O2.
