-Subject: [PATCH] ranger: Fix up fold_using_range::range_of_address [PR103255]
-
-If on &base->member the offset isn't constant or isn't zero and
--fdelete-null-pointer-checks and not -fwrapv-pointer and base has a range
-that doesn't include NULL, we return the range of the base.
-Usually it isn't a big deal, because for most pointers we just use
-varying, range_zero and range_nonzero ranges and nothing beyond that,
-but if a pointer is initialized from a constant, we actually track the
-exact range and in that case this causes miscompilation.
-As discussed on IRC, I think doing something like:
- offset_int off2;
- if (off_cst && off.is_constant (&off2))
- {
- tree cst = wide_int_to_tree (sizetype, off2 / BITS_PER_UNIT);
- // adjust range r with POINTER_PLUS_EXPR cst
- if (!range_includes_zero_p (&r))
- return true;
- }
- // Fallback
- r = range_nonzero (TREE_TYPE (gimple_assign_rhs1 (stmt)));
- return true;
-could work, given that most of the pointer ranges are just the simple ones
-perhaps it is too much for little benefit.

- range_nonzero rather than unadjusted base's range. Formatting fixes.

-X-Git-Tag: releases/gcc-11.3.0~445
-X-Git-Url: https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff_plain;h=01a70ccd723eb9a479186fe37c972b0d0f8676cf

-libstdc++: Add -nostdinc++ for c++17 sources [PR100017]
-
-When building a build!=host compiler, the just-built gcc can't be used
-to build the target libstdc++ (because it is built for the host triplet,
-not the build triplet). The top-level configure.ac sets up the build
-flags for libstdc++ (and other "raw_cxx" libs) like this:
-
-GCC_TARGET_TOOL(c++ for libstdc++, RAW_CXX_FOR_TARGET, CXX,
- [gcc/xgcc -shared-libgcc -B$$r/$(HOST_SUBDIR)/gcc -nostdinc++ -L$$r/$(TARGET_SUBDIR)/libstdc++-v3/src -L$$r/$(TARGET_SUBDIR)/libstdc++-v3/src/.libs -L$$r/$(TARGET_SUBDIR)/libstdc++-v3/libsupc++/.libs],
- c++)
-
-The -nostdinc++ flag is only used for the IN-TREE-TOOL, i.e. when using
-the just-built gcc/xgcc compiler. This means that the cross-compiler
-used to build libstdc++ will add its own libstdc++ headers to the
-include path. That results in the #include <cfenv> in
-src/c++17/floating_to_chars.cc and src/c++17/floating_from_chars.cc
-doing #include_next <fenv.h> and finding the libstdc++ fenv.h wrapper
-from the host compiler. Because that has the same include guard as the
-<fenv.h> in the libstdc++ we're trying to build, we never reach the
-underlying <fenv.h> from libc. That results in several errors of the
-form:
-
-error: 'fenv_t' has not been declared in '::'
-
-The most correct fix would be to add -nostdinc++ to the
-RAW_CXX_FOR_TARGET variable in configure.ac, or the
-RAW_CXX_TARGET_EXPORTS variable in Makefile.tpl.
-
-Another solution would be to make the libstdc++ <fenv.h> wrapper use
-_GLIBCXX_INCLUDE_NEXT_C_HEADERS like our <stdlib.h> and other C header
-wrappers.
-
-For now though, the simplest and safest solution is to just add
--nostdinc++ to the CXXFLAGS used for src/c++17/*.cc, which is what this
-does.
