Hi,
this patch fixes testsuite PR80220 - "relative line numbers don't work
when put between braces".
Consider gcc/testsuite/gcc.dg/990506-0.c, which has absolute line
numbers between braces:
...
$ cat -n 990506-0.c
1 /* Verify that a diagnostic is issued without crashing due to
2
In stage1 with -std=gnu++98 I see:
/home/markus/gcc/gcc/tree.c: In function ‘void inchash::add_expr(const_tree,
inchash::hash&, unsigned int)’:
/home/markus/gcc/gcc/tree.c:8013:11: warning: name lookup of ‘i’ changed
for (i = TREE_OPERAND_LENGTH (t) - 1; i >= 0; --i)

A dumb mistake on my part, we can have a self-referencing definition
statement inside a loop. That will cause the recently added code to
walk back through BIT_IOR_EXPRs to recurse forever.
I've added a trivial recursion depth limit.

Hi all,
I intend to commit the attached patch for a problem with derived-type
I/O and namelist output by tomorrow, if there are no objections. The
dtio_25.f90 test case needed some adjustments (see the discussion on
bugzilla) and still contains a FIXME note, which will be fixed by
Jerry's upcoming
The attached patch optimizes the atomic_exchange and
atomic_compare patterns on s390 and s390x (mostly limited to
SImode and DImode). Among general optimizaation, the changes fix
most of the problems reported in PR 80080:

Building older GCC releases with clang tends to issue warnings. This

The code in fold_comparison calls save_expr on an expression and then tries to
set a location of the expression. But since save_expr calls fold, it can
produce an integer constant, so we must be more careful when setting its
