Follow aarch64 and riscv ports by using (global ? DW_EH_PE_indirect : 0)
| DW_EH_PE_pcrel for -fno-pic code. This avoids a canonical PLT entry
for a personality reference in .eh_frame and a copy relocation for a
typeinfo reference in .gcc_except_table, when the definition is in
libstdc++.so.6.

Update documentation to clarify a GCC extension on structure with

gcc/ChangeLog:
* doc/extend.texi: Document GCC extension on a structure containing
a flexible array member to be a member of another structure.

This is the patch for PR101832, to fix builtin_object_size to
correctly handle component_ref to a structure/union field that
includes a flexible array member.
also includes a documentation update for the GCC extension on embedding
a structure/union with flexible array member into another
GCC extension accepts the case when a struct with a flexible array member
is embedded into another struct (possibly recursively).
__builtin_object_size should treat such struct as flexible size per

The patch that added support for fmin/fmax reductions didn't
handle single def-use cycles. In some ways, this seems like
going out of our way to make things slower, but that's a
discussion for another day.
Tested on aarch64-linux-gnu & x86_64-linux-gnu. OK for trunk
and the GCC 12 branch?

Yeah, odd. The C and C++ FEs indeed diagnose non-pow2p constants
for align (and not for aligned
Yeah that shouldn't be there, it's from an earlier version of the patch
I wrote where I was experimenting changing the existing modes, I'll
