The repeated checks for MEM_REF made this code hard to convert to
poly_ints as-is. Hopefully the new structure also makes it clearer
at a glance what the two cases are.

SVE needs a way of broadcasting a scalar to a variable-length vector.
This patch adds VEC_DUPLICATE_EXPR for when CONSTRUCTOR would be used
for fixed-length vectors; this is the tree equivalent of the existing
rtl code VEC_DUPLICATE.
The patch also adds a vec_duplicate_optab to go with VEC_DUPLICATE_EXPR.

missing -Wformat-overflow with %s and non-member array arguments
-Wformat-overflow uses the routine "get_range_strlen" to decide the
maximum string length, however, currently "get_range_strlen" misses
the handling of non-member arrays.
Adding the handling of non-member array resolves the issue.
Adding test case pr79538.c into gcc.dg.
During gcc bootstrap, 2 source files (c-family/c-cppbuiltin.c,
fortran/class.c) were detected new warnings by -Wformat-overflow
due to the new handling of non-member array in "get_range_strlen".
in order to avoid these new warnings and continue with bootstrap,
updating these 2 files to avoid the warnings.
in c-family/c-cppbuiltin.c, the warning is following:
../../latest_gcc_2/gcc/c-family/c-cppbuiltin.c:1627:15: note:
‘sprintf’ output 2 or more bytes (assuming 257) into a destination
of size 256
sprintf (buf1, "%s=%s", macro, buf2);
~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~
in the above, buf1 and buf2 are declared as:
char buf1[256], buf2[256];
i.e, buf1 and buf2 have same size. adjusting the size of buf1 and
buf2 resolves the warning.
fortran/class.c has the similar issue as above. Instead of adjusting
size of the buffers, replacing sprintf with xasprintf is a better
solution for these cases.
