Apparently, quite some places in the compiler (like the C/C++
preprocessor, the debug info machinery) expect expand_location to
resolve to locations that are in the main source file, even if the
token at stake comes from a macro that was defined in a header
somewhere. Turning on -ftrack-macro-expansion by default was
triggering a lot of failures (not necessarily related to diagnostics)
because expand_location resolves to spelling locations instead.
So I have changed expand_location to honour the initial expectation.
In addition, I came up with the new expand_location_to_spelling_point
used in diagnostic_build_prefix because the diagnostic system, on the
other hand, wants to point to the location of the token where it was
spelled, and then display the error context involving all the macro
whose expansion led to that spelling point - if we are in the context
of a macro expansion there.
This seems to me like a reasonable balance.
Tested and bootstrapped on x86_64-unknown-linux-gnu against trunk and
whitnessed that a lot more tests were PASSing.
Note that the bootstrap with -ftrack-macro-expansion exhibits other
separate issues that are addressed in subsequent patches. This patch
just fixes one class of problems.
The patch does pass bootstrap with -ftrack-macro-expansion turned off,
though.

Consider the test case gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c.
Its interesting part is:
#define A(x) vari x /* line 7. */
#define vari(x)
#define B , varj
int A(B) ; /* line 10. */
In its initial version, this test was being pre-processed as:
# 1 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
# 1 "build/gcc//"
# 1 "<command-line>"
# 1 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
# 10 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
int
# 7 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
vari
, varj ;
Note how "int" and "vari" are on separate lines, whereas "int" and
", varj" are on the same line.
This looks like a bug to me, even independantly from the macro
location tracking work.
With macro location tracking turned on, the preprocessed output
becomes:
# 1 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
# 1 "<command-line>"
# 1 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
# 10 "gcc/testsuite/gcc.dg/debug/dwarf2/pr41445-5.c"
int vari , varj ;
Which, IMO, is what we'd expect.
This is due to an unexpected side effect of enter_macro_context when
passed a token that might look like a function-like macro at first
sight, but that it eventually considers to not be a macro after all.
This is the case for the "vari" token which looks like a macro when it
is first lexed, but is eventually considered to be a normal token by
enter_macro_context because it's not used as a function-like macro
invocation.
In that case, besides returning NULL, enter_macro_context sets
pfile->context->c.macro to NULL, making cpp_get_token_1 forget to set
the location of the "vari" to the expansion point of A.
enter_macro_context sets pfile->context->c.macro to NULL in that case
because funlike_invocation_p reads one token pass "foo", sees that
there is no '(' token, so we are not invoking the function-like
parameter. It then puts the tokens (which it has read after "foo")
back into the tokens stream by calling _cpp_push_token_context on it,
which sets pfile->context->c.macro to NULL, saying in essence that the
current macro expansion context is "stopped".
The fix here is to teach _cpp_push_token and
push_extended_tokens_context to continue the current macro context
when passed a NULL macro. But then, now that there can be several
continguous contexts associated with the same macro, we need to teach
_cpp_pop_context to re-enable the expansion of the current macro only
when we are really out of expanding the current macro. Otherwise we
can run in cases where we have recursive expansions of the same macro.
Tested on x86_64-unknown-linux-gnu against trunk. Now this test has
the same output with and without tracking locations accross macro
expansions.

separate issues that are addressed in subsequent patches. This patch

When -ftrack-macro-expansion is activated, the PCH generation
machinery can crash in gt_pch_save when it's about to relocate the
pointer for the
line_maps::info_macro::maps[i]::d.macro.macro_locations member.
The call that crashes (in ggc-common.c) is:
state.ptrs[i]->note_ptr_fn (state.ptrs[i]->obj,
state.ptrs[i]->note_ptr_cookie,
relocate_ptrs, &state);
The ->note_ptr_fn called in this case is the gengtype-generated
gt_pch_p_9line_maps function. It crashes because the second argument
passed to it is a pointer to struct line_map, instead of being a
pointer to struct line_maps (extra 's') like what the function
expects.
You can see the crash for the test case:
runtest --tool g++ --tool_opts="-ftrack-macro-expansion" pch.exp=system-1.C
I believe it's because a part of the code of gt_pch_nx_line_maps
(generated as part of gtype-desc.c by gengtype) is not correct. Note
that this gt_pch_nx_line_maps function is called from gt_pch_save in
the snippet:
for (rt = gt_ggc_rtab; *rt; rt++)
for (rti = *rt; rti->base != NULL; rti++)
for (i = 0; i < rti->nelt; i++)
(*rti->pchw)(*(void **)((char *)rti->base + rti->stride * i));
So, in that gt_pch_nx_line_maps, in the branch that starts with the
code:
if ((*x).info_macro.maps != NULL) {
size_t i3;
for (i3 = 0; i3 != (size_t)(((*x).info_macro).used); i3++) {
switch (((*x).info_macro.maps[i3]).reason == LC_ENTER_MACRO)
we have the code:
gt_pch_note_object ((*x).info_macro.maps[i3].d.macro.macro_locations,
(*x).info_macro.maps,
gt_pch_p_9line_maps,
gt_types_enum_last);
This last snippet registers gt_pch_p_9line_maps to be called on the
object pointed by (*x).info_macro.maps[i3].d.macro.macro_locations (as
a first argument), with (*x).info_macro.maps as its second argument.
Note that (*x).info_macro.maps is of type struct line_map*, while 'x'
is of type struct line_maps* - beware, there is an 's' at the end of
the latter.
The problem is that gt_pch_p_9line_maps requires that its second
argument be an instance of _struct line_maps_, not struct line_map.
So later when gt_pch_p_9line_maps is called, it just crashes.
More generally, these gt_pch_p_xxx functions seem to require that
their second argument be an instance of the xxx in question. And that
invariant is violated by the snippet of code above.
The invariant seems to be violated only for the case where a GTYed
structure (possibly embedded in another GTYed structure) contains a
pointer to a scalar (that is not a string) which memory is ggc/GTY
managed, like the line_map_macro::macro_locations field. And this
only happens for PCH generation.
Looking at gengtype.c, it seems like write_types_process_field can be
fooled in that case. It expects that the expression d->prev_val[3]
contains the name of the second argument of the gt_pch_p_xxx (which is
generically referenced by wtd->subfield_marker_routine there). That
expression can resolve to either "x", as we would like it to be, but
can also resolve to another arbitrary name for e.g, the case of a
pointer-to-struct used as a root).
This patch simply forces the second argument of gt_pch_p_xxx to be 'x'
even in the case of a member that is a pointer to a scalar.

This option, which is enabled by default, causes the preprocessor to warn
when a string or character literal is followed by a ud-suffix which does
not begin with an underscore. According to [lex.ext]p10, this is
ill-formed.
Also modifies the preprocessor to treat such ill-formed suffixes as separate
preprocessing tokens. This is consistent with the Clang front end (see
http://llvm.org/viewvc/llvm-project?view=rev&revision=152287), and enables
backwards compatibility with code that uses formatting macros from
