Track from which abstract lexical block concrete ones come from in DWARF
so that debuggers can inherit the former from the latter. This enables
debuggers to properly handle the following case:
* function Child2 is nested in a lexical block, itself nested in
function Child1;
* function Child1 is inlined into some call site;
* function Child2 is never inlined.
Here, Child2 is described in DWARF only in the abstract instance of
Child1. So when debuggers decode Child1's concrete instances, they need
to fetch the definition for Child2 in the corresponding abstract
instance: the DW_AT_abstract_origin link on the lexical block that
embeds Child1 enables them to do that.
Bootstrapped and regtested on x86_64-linux.
gcc/ChangeLog:
* dwarf2out.c (add_abstract_origin_attribute): Adjust
documentation comment. For BLOCK nodes, add a
DW_AT_abstract_origin attribute that points to the DIE generated
for the origin BLOCK.
(gen_lexical_block_die): Call add_abstract_origin_attribute for
blocks from inlined functions.

expand_debug_expr handled negative bit positions using:
else if (bitpos < 0)
{
HOST_WIDE_INT units
= (-bitpos + BITS_PER_UNIT - 1) / BITS_PER_UNIT;
op0 = adjust_address_nv (op0, mode1, units);
bitpos += units * BITS_PER_UNIT;
}
Here "units" is the negative of the (negative) byte offset, so I think
we should be offsetting OP0 by -units instead. E.g. a bitpos of -17
would give units==3, so this code would move OP0 up by 3 bytes and set
bitpos to 7, giving a total bitpos of 31.
Just noticed by inspection. An assert triggered for:
gcc.target/i386/mpx/bitfields-1-lbv.c
gcc.target/i386/mpx/field-addr-7-lbv.c
gcc.target/i386/mpx/reference-3-lbv.cpp
gcc.target/i386/mpx/reference-4-lbv.cpp
at -m32 but otherwise this case doesn't seem to trigger during a
bootstrap and regtest.
Tested on x86_64-linux-gnu.

wide_int_constant_multiple_p used:
if (*mult_set && mult != 0)
return false;
to check whether we had previously seen a nonzero multiple, but "mult" is
a pointer to the previous value rather than the previous value itself.
Noticed by inspection while working on another patch, so I don't have a
testcase. I tried adding an assert for combinations that were wrongly
rejected before but it didn't trigger during a bootstrap and regtest.
