All uses of _GL_UNUSED_PARAMETER (after parameters) replaced by _GL_ATTRIBUTE_MAYBE_UNUSED (before parameters). Although perhaps we need a shorter name for _GL_ATTRIBUTE_MAYBE_UNUSED, that should probably be in gnulib-common.m4, due to the ubiquity of this issue. And perhaps the snippet/unused-parameter module should be marked obsolete since it's no longer compatible with its old use. * m4/gnulib-common.m4 (gl_COMMON_BODY): Define the macro _GL_HAS_C_ATTRIBUTE, and use it instead of __STDC_VERSION__ in deciding whether to use C2x attributes like [[__deprecated__]].

Fix this by defining xalloc_oversized (n, s) to work even if s == 0. * lib/malloca.h, lib/xalloc-oversized.h: Document new behavior. * lib/xalloc-oversized.h (__xalloc_oversized): Do not crash if S==0. * tests/test-reallocarray.c (main): Test for the bug.
* reallocarray: check for ptrdiff_t overflowPaul Eggert2021-04-241-16/+21
| | | | | | | | | | | | | | | | * doc/glibc-functions/reallocarray.texi (reallocarray): Mention ptrdiff_t overflow. * lib/reallocarray.c (reallocarray): Reindent as per usual GNU. * lib/stdlib.in.h (reallocarray): Allow reallocarray to be replaced. * m4/reallocarray.m4 (gl_FUNC_REALLOCARRAY): Check for ptrdiff_t overflow. * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Set up REPLACE_REALLOCARRAY. * modules/reallocarray (Files): Add malloc.m4. (configure.ac): Also test REPLACE_REALLOCARRAY. * modules/reallocarray-tests (Depends-on): Add stdint. * modules/stdlib (stdlib.h): Substitute REPLACE_REALLOCARRAY. * tests/test-reallocarray.c: Include stdint.h. (main): Check for ptrdiff_t overflow.
* calloc-gnu-tests: add overflow testsPaul Eggert2021-04-241-21/+16
| | | | | | * tests/test-calloc-gnu.c (identity): New function, replacing ‘eight’. (main): Do 2 * log2(SIZE_MAX) tests instead of just two tests. Don’t bother to free on failure.
* execute-tests: pacify compilerPaul Eggert2021-04-211-3/+3
| | | | | | * tests/test-execute-main.c (main): Use 0x7DEADBEE rather than 0xDEADBEEF for nonces, to avoid provoking AIX XLC compiler warning that the latter is out of int range.
* malloc-gnu-tests, etc.: use volatile for clangPaul Eggert2021-04-207-17/+20
| | | | | | | | | | | | | | | In some more test locations, store the result of malloc etc. into a volatile pointer so that clang doesn’t optimize away the malloc and thus bypass the test. This fixes a malloc-gnu test failure on macOS 11.2.3 with clang 12.0.0 on ARM. * tests/test-alloca-opt.c (do_allocation): * tests/test-malloc-gnu.c (main): * tests/test-malloca.c (do_allocation): * tests/test-realloc-gnu.c (main): * tests/test-reallocarray.c (main): * tests/test-aligned-malloc.c (main): * tests/test-aligned_alloc.c (main): Store malloc etc. results into a volatile pointer.
* malloc-gnu-tests: pacify -Walloc-size-larger-thanPaul Eggert2021-04-182-6/+6
| | | | | | | | * tests/test-malloc-gnu.c (main): * tests/test-realloc-gnu.c (main): Hide true intentions from GCC, to prevent diagnostics like “warning: argument 1 value ‘9223372036854775808’ exceeds maximum object size 9223372036854775807 [-Walloc-size-larger-than=]”.
