generic package body.
gcc/ada/
2017-12-15 Ed Schonberg <schonberg@adacore.com>
* exp_unst.adb (Unnest_Subprograms): Nothing to do if the main unit is
a generic package body. Unnesting is only an issue when generating
code, and if the main unit is generic then nested instance bodies have
not been created and analyzed, and unnesting will crash in the absence
of those bodies,

(Build_Call_Marker): Do not create a marker for a call which originates
from an expanded spec or body of an instantiated gener, does not invoke
a generic formal subprogram, the target is external to the instance,
and -gnatdL is in effect.

* sem_ch6.adb (Possible_Freeze): Do not set Delayed_Freeze on an
subprogram instantiation, now that the enclosing wrapper package
carries an explicit freeze node. THis prevents freeze nodes for the
subprogram for appearing in the wrong scope. This is relevant when the
generic subprogram has a private or incomplete formal type and the
instance appears within a package that declares the actual type for the
instantiation, and that type has itself a delayed freeze.

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.

This patch adds an -mverbose-cost-dump option, similar to the one in aarch64.
It makes the RTX cost dump print the RTX we're costing in the backend, as well as its cost.
This can be distracting in other cost-related RTL dumps like combine's.
So now we don't dump the backend information by default, but provide the power-user option -mverbose-cost-dump
to enable the old verbose dumping.
This option is for GCC developers debugging the compiler only, so no documentation are added.
It's also trivially simple in functionality so no test is added either.
Bootstrapped and tested on arm-none-linux-gnueabihf.
Committed to trunk.

* reload1.c (emit_input_reload_insns): Skip debug markers.
From-SVN: r255640

We skip debug insns and notes after a call that needs a nop_endbr, but
since a debug insn could be the last in a block, it may affect the loc
in the emitted nop_endbr insn. Although this has no effect on
codegen, it does mess with debug info a bit, and it causes
-fcompare-debug to fail for e.g. libsanitizer's
tsan/tsan_platform_linux.cc on x86_64.
So, pick the location of the call insn for the nop_endbr insn, to
avoid the line number differences in dumps, including -fcompare-debug
ones.
Also, we don't need to determine what the insert point would be unless
we're actually emitting the nop_endbr insn after the call, so
rearrange the code to avoid wasting cycles.
Finally, it seems like testing for barriers is a mistake. We probably
never actually pass that test, for the barriers would hit BB_END
first. If we did, we'd end up emitting the nop_endbr outside any BB,
even after the end of the function! That would be Very Bad (TM).
Now, since the test as it is can't hurt, I figured I wouldn't change
the logic right now, just add a comment so that someone involved in
endbr stuff can have a second look and hopefully fix it.

This patch is a follow up to the existing discussions on
https://gcc.gnu.org/ml/gcc-patches/2017-07/msg01904.html
Bin had earlier submitted this patch to fix the ICE that
occurs because of the missing LTGT in aarch64-simd.md.
That discussion opened up a new bug report PR81647 for
an inconsistent behavior.
As discussed earlier on the gcc-patches discussion and on
the bug report, PR81647 was occurring because of how UNEQ
was handled in aarch64-simd.md rather than LTGT.
Since __builtin_islessgreater is guaranteed to not give an
FP exception but LTGT might, __builtin_islessgreater gets
converted to ~UNEQ very early on in fold_builtin_unordered_cmp.
Thus I will post a separate patch for correcting how UNEQ and
other unordered comparisons are handled in aarch64-simd.md.
This patch is only adding the missing LTGT to plug the ICE.
Testing done: Checked for regressions on bootstrapped
aarch64-none-linux-gnu and added a new compile time test case
that gives out LTGT to make sure it doesn't ICE

of the form:
C0 + C1*X1 + C2*X2 ... + Cn*Xn
It also adds poly_int-based typedefs for offsets and sizes of various
precisions. In these typedefs, the Ci coefficients are compile-time
constants and the Xi indeterminates are run-time invariants. The number
of coefficients is controlled by the target and is initially 1 for all
ports.
Most routines can handle general coefficient counts, but for now a few
are specific to one or two coefficients. Support for other coefficient
counts can be added when needed.
The patch also adds a new macro, IN_TARGET_CODE, that can be
set to indicate that a TU contains target-specific rather than
target-independent code. When this macro is set and the number of
coefficients is 1, the poly-int.h classes define a conversion operator
to a constant. This allows most existing target code to work without
modification. The main exceptions are:
- values passed through ..., which need an explicit conversion to a
constant
- ?: expression in which one arm ends up being a polynomial and the
other remains a constant. In these cases it would be valid to convert
the constant to a polynomial and the polynomial to a constant, so a
cast is needed to break the ambiguity.
The patch also adds a new target hook to return the estimated
value of a polynomial for costing purposes.
The patch also adds operator<< on wide_ints (it was already defined
for offset_int and widest_int). I think this was originally excluded
because >> is ambiguous for wide_int, but << is useful for converting
bytes to bits, etc., so is worth defining on its own. The patch also
adds operator% and operator/ for offset_int and widest_int, since those
types are always signed. These changes allow the poly_int interface to
be more predictable.
I'd originally tried adding the tests as selftests, but that ended up
bloating cc1 by at least a third. It also took a while to build them
at -O2. The patch therefore uses plugin tests instead, where we can
force the tests to be built at -O0. They still run in negligible time
when built that way.
