This commit adds the -fmacro-prefix-map option that allows remapping of file
names in __FILE__, __BASE_FILE__, and __builtin_FILE(), similar to how
-fdebug-prefix-map allows to do the same for debug information.
Additionally, it adds -ffile-prefix-map which can be used to specify both
mappings with a single option (and, should we need to add more -f*-prefix-map
options in the future, those as well).

This patch changes GET_MODE_NUNITS from unsigned char
to poly_uint16, although it remains a macro when compiling
target code with NUM_POLY_INT_COEFFS == 1.
We can handle permuted loads and stores for variable nunits if
the number of statements is a power of 2, but not otherwise.
The to_constant call in make_vector_type goes away in a later patch.

This patch changes the types of the bit offsets and sizes returned
by get_ref_base_and_extent to poly_int64.
There are some callers that can't sensibly operate on polynomial
offsets or handle cases where the offset and size aren't known
exactly. This includes the IPA devirtualisation code (since
there's no defined way of having vtables at variable offsets)
and some parts of the DWARF code. The patch therefore adds
a helper function get_ref_base_and_extent_hwi that either returns
exact HOST_WIDE_INT bit positions and sizes or returns a null
base to indicate failure.

This patch makes the DWARF code use poly_int64 rather than
HOST_WIDE_INT for CFA offsets. The main changes are:
- to make reg_save use a DW_CFA_expression representation when
the offset isn't constant and
- to record the CFA information alongside a def_cfa_expression
if either offset is polynomial, since it's quite difficult
to reconstruct the CFA information otherwise.

This patch changes SUBREG_BYTE from an int to a poly_int.
Since valid SUBREG_BYTEs must be contained within the mode of the
SUBREG_REG, the required range is the same as for GET_MODE_SIZE,
i.e. unsigned short. The patch therefore uses poly_uint16(_pod)
for the SUBREG_BYTE.
Using poly_uint16_pod rtx fields requires a new field code ('p').
Since there are no other uses of 'p' besides SUBREG_BYTE, the patch
doesn't add an XPOLY or whatever; all uses should go via SUBREG_BYTE
instead.
The patch doesn't bother implementing 'p' support for legacy
define_peepholes, since none of the remaining ones have subregs
in their patterns.
As it happened, the rtl documentation used SUBREG as an example of a
code with mixed field types, accessed via XEXP (x, 0) and XINT (x, 1).
Since there's no direct replacement for XINT, and since people should
never use it even if there were, the patch changes the example to use
INT_LIST instead.
The patch also changes subreg-related helper functions so that they too
take and return polynomial offsets. This makes the patch quite big, but
it's mostly mechanical. The patch generally sticks to existing choices
wrt signedness.

This patch changes the MEM_OFFSET and MEM_SIZE memory attributes
from HOST_WIDE_INT to poly_int64. Most of it is mechanical,
but there is one nonbovious change in widen_memory_access.
Previously the main while loop broke with:
/* Similarly for the decl. */
else if (DECL_P (attrs.expr)
&& DECL_SIZE_UNIT (attrs.expr)
&& TREE_CODE (DECL_SIZE_UNIT (attrs.expr)) == INTEGER_CST
&& compare_tree_int (DECL_SIZE_UNIT (attrs.expr), size) >= 0
&& (! attrs.offset_known_p || attrs.offset >= 0))
break;
but it seemed wrong to optimistically assume the best case
when the offset isn't known (and thus might be negative).
As it happens, the "! attrs.offset_known_p" condition was
always false, because we'd already nullified attrs.expr in
that case:
/* If we don't know what offset we were at within the expression, then
we can't know if we've overstepped the bounds. */
if (! attrs.offset_known_p)
attrs.expr = NULL_TREE;
The patch therefore drops "! attrs.offset_known_p ||" when
converting the offset check to the may/must interface.

This patch adds support for DWARF location expressions
that involve polynomial offsets. It adds a target hook that
says how the runtime invariants used in the offsets should be
represented in DWARF. SVE vectors have to be a multiple of
128 bits in size, so the GCC port uses the number of 128-bit
blocks minus one as the runtime invariant. However, in DWARF,
the vector length is exposed via a pseudo "VG" register that
holds the number of 64-bit elements in a vector. Thus:
indeterminate 1 == (VG / 2) - 1
The hook needs to be general enough to express this.
Note that in most cases the division and subtraction fold
away into surrounding expressions.

This patch adds an rtl representation of poly_int values.
There were three possible ways of doing this:
(1) Add a new rtl code for the poly_ints themselves and store the
coefficients as trailing wide_ints. This would give constants like:
(const_poly_int [c0 c1 ... cn])
The runtime value would be:
c0 + c1 * x1 + ... + cn * xn
(2) Like (1), but use rtxes for the coefficients. This would give
constants like:
(const_poly_int [(const_int c0)
(const_int c1)
...
(const_int cn)])
although the coefficients could be const_wide_ints instead
of const_ints where appropriate.
(3) Add a new rtl code for the polynomial indeterminates,
then use them in const wrappers. A constant like c0 + c1 * x1
would then look like:
(const:M (plus:M (mult:M (const_param:M x1)
(const_int c1))
(const_int c0)))
There didn't seem to be that much to choose between them. The main
advantage of (1) is that it's a more efficient representation and
that we can refer to the cofficients directly as wide_int_storage.

This patch adjusts numerous parts of the compiler that would
malfunction should they find debug markers at points where they may be
introduced. The changes purport to allow the compiler to pass
bootstrap-debug-lean (-fcompare-debug in stage3) at various
optimization levels, as well as bootstrap-debug-lib (-fcompare-debug
for target libraries), even after the compiler is changed so that
debug markers are introduced in code streams at spots where earlier
debug stmts, insns and notes wouldn't normally appear.
This patch depends on an earlier SFN boilerplate patch, and on another
SFN patch that introduces new RTL insn-walking functions.

Early debug broke generation of .debug_rnglists when using both -gdwarf5
and -gsplit-dwarf. It introduces a generation for init_sections_and_labels,
but doesn't account for the generation of up to 4 unique ranges labels,
two created in init_sections_and_labels and two in output_rnglists.
Fix this by passing generation to output_rnglists and creating 4 unique
labels per generation.
Without this fix using -gdwarf-5 -gsplit-dwarf could result in:
Error: symbol `.Ldebug_ranges2' is already defined

Unlike bootstrap-debug, bootstrap-debug-lean used to pass compare using
the traditional compare command, because it compiled both stage2 and
stage3 with options that used to generate identical output
(-fcompare-debug= in stage2 vs -fcompare-debug in stage3).
Since we started adding relevant command-line flags to DW_AT_producer,
this is no longer the case, and stages 2 and 3 object files that differ
in nothing but the DW_AT_producer strings.
-fcompare-debug is short for -fcompare-debug=-gtoggle, so stage3
compiles twice, once with the normal options, once with toggled -g, to
then compare the temporary final dumps. When enabled, both compilations
get from the driver an additional -frandom-seed flag (if none is given
explicitly).
-fcompare-debug= is short for -fno-compare-debug, disabling the second
compilation.
The difference between the DW_AT_producer lines are the different
-fcompare-debug flags, and the presence of the -frandom-seed flag in the
stage3 compilation.
It is easy and sensible enough to filter the -fcompare-debug flags out
of the DW_AT_producer string. This option should never affect the
compilation output, it just determines whether or not to perform an
additional compilation that should produce the same executable output.
However, dropping -frandom-seed is not quite correct, in that it might
have other consequences on the compilation. So, it makes little sense
to make the effort to drop it when it's implicit; for those comparing
compiler output differences, it might even hint at what causes, and
could fix, difficult to explain differences, namely, explicitly
supplying -frandom-seed options.
They don't seem to matter for compiler bootstraps, though, at least
for now, so we can safely refrain from issuing -frandom-seed (or maybe
we already issue it where needed :-), and then, for
bootstrap-debug-lean, use the compare-debug script, that strips out
debug information before comparing the object files.

FT32 makes use of multiple address spaces. When trying to inspect
objects in GDB, GDB was treating them as a straight "const". The cause
seems to be in GCC DWARF2 output.
This output is handled in gcc/gcc/dwarf2out.c, where modified_type_die()
checks that TYPE has qualifiers CV_QUALS. However while TYPE has
ADDR_SPACE qualifiers, the modified_type_die() explicitly discards the
ADDR_SPACE qualifiers.
This patch retains the ADDR_SPACE qualifiers as modified_type_die()
outputs the DWARF type tree. This allows the types to match, and correct
type information for the object is emitted.

C17, a bug-fix version of the C11 standard with DR resolutions
integrated, will soon go to ballot. This patch adds corresponding
options -std=c17, -std=gnu17 (new default version, replacing
-std=gnu11 as the default), -std=iso9899:2017. As a bug-fix version
of the standard, there is no need for flag_isoc17 or any options for
compatibility warnings; however, there is a new __STDC_VERSION__
value, so new cpplib languages CLK_GNUC17 and CLK_STDC17 are added to
support using that new value with the new options. (If the standard
ends up being published in 2018 and being known as C18, option aliases
can be added. Note however that -std=iso9899:199409 corresponds to a
__STDC_VERSION__ value rather than a publication date.)
(There are a couple of DR resolutions needing implementing in GCC, but
that's independent of the new options.)
(I'd propose to add -std=c2x / -std=gnu2x / -Wc11-c2x-compat for the
next major C standard revision once there are actually C2x drafts
being issued with new features included.)
Bootstrapped with no regressions for x86_64-pc-linux-gnu.

The wide_int routines allow things like:
wi::add (t, 1)
to add 1 to an INTEGER_CST T in its native precision. But we also have:
wi::to_offset (t) // Treat T as an offset_int
wi::to_widest (t) // Treat T as a widest_int
Recently we also gained:
wi::to_wide (t, prec) // Treat T as a wide_int in preccision PREC
This patch therefore requires:
wi::to_wide (t)
when operating on INTEGER_CSTs in their native precision. This is
just as efficient, and makes it clearer that a deliberate choice is
being made to treat the tree as a wide_int in its native precision.
This also removes the inconsistency that
a) INTEGER_CSTs in their native precision can be used without an accessor
but must use wi:: functions instead of C++ operators
b) the other forms need an explicit accessor but the result can be used
with C++ operators.
It also helps with SVE, where there's the additional possibility
that the tree could be a runtime value.

This patch is an attempt to fix the crash reported in PR82155.
When generating a C++ class method for a class that is itself nested in
a class method, dwarf2out_early_global_decl currently leaves the
existing context DIE as it is if it already exists. However, it is
possible that this call happens at a point where this context DIE is
just a declaration that is itself not located in its own context.
From there, if dwarf2out_early_global_decl is not called on any of the
FUNCTION_DECL in the context chain, DIEs will be left badly scoped and
some (such as the nested method) will be removed by the type pruning
machinery. As a consequence, dwarf2out_abstract_function will will
crash when called on the corresponding DECL because it asserts that the
DECL has a DIE.
This patch fixes this crash making dwarf2out_early_global_decl process
context DIEs the same way we process abstract origins for FUNCTION_DECL:
if the corresponding DIE exists but is only a declaration, call
dwarf2out_decl anyway on it so that it is turned into a more complete
DIE and so that it is relocated in the proper context.
Bootstrapped and regtested on x86_64-linux.

This patch that adds -g to the set of negatable prefixes along with -f,
-m and -W. Besides the mapping from -gno- to negated -g in option_map
and adding g to the [fmW] matches for negatable options, I had to
introduce gno- as an remapping prefix, for the option searching
machinery to backtrack to and recognize as a remapping prefix, instead
of backtracking to -g and stopping at it as if no-* was its Joined
argument. Adding such remapping prefixes to preempt further
backtracking can be accomplished by introducing the prefix as an
Undocumented option with a Joined argument and without Driver, Target,
Common, or any language-specific option. Whenever we match such a fake
options prefix, we abandon further backtracking (it matches, after all),
but find_opt returns the same code it would if it hadn't found any
match, so that we resort to option mapping.
I've arranged for such remapping prefixes to not be considered when
looking for and suggesting a correct spelling for misspelled options.
While testing that, I found a few -W-started options that were not
marked as RejectNegative but should (-Wno-a, is not something we'd like
to suggest ;-) I've also marked as such -g-started options that
it makes no sense to negate, and removed the explicit -gno- ones,
allowing their opposites to be negated.

This patch treats the mode associated with an integer constant as a
scalar_mode. We can't use the more natural-sounding scalar_int_mode
because we also use (const_int 0) for bounds-checking modes. (It might
be worth adding a bounds-specific code instead, but that's for another
day.)
This exposes a latent bug in simplify_immed_subreg, which for
vectors of CONST_WIDE_INTs would pass the vector mode rather than
the element mode to rtx_mode_t.
I think the:
/* We can get a 0 for an error mark. */
|| GET_MODE_CLASS (mode) == MODE_VECTOR_INT
|| GET_MODE_CLASS (mode) == MODE_VECTOR_FLOAT
in immed_double_const is dead. trunc_int_mode (via gen_int_mode)
would go on to ICE if the mode fitted in a HWI, and surely plenty
of other code would be confused to see a const_int be interpreted
as a vector. We should instead be using CONST0_RTX (mode) if we
need a safe constant for a particular mode.
We didn't try to make these functions take scalar_mode arguments
because in many cases that would be too invasive at this stage.
Maybe it would become feasible in future. Also, the long-term
direction should probably be to add modes to constant integers
rather than have then as VOIDmode odd-ones-out. That would remove
the need for rtx_mode_t and thus remove the question whether they
should use scalar_int_mode, scalar_mode or machine_mode.
The patch also uses scalar_mode for the CONST_DOUBLE handling
in loc_descriptor. In that case the mode can legitimately be
either floating-point or integral.

This patch changes the types of various things from machine_mode
to scalar_int_mode, in cases where (after previous patches)
simply changing the type is enough on its own. The patch does
