2021-11-29Make etags path used by build system configurableEric Gallager3-1/+14
This commit allows users to specify a path to their "etags" executable for use when doing "make tags". I based this patch off of this one from upstream automake: https://git.savannah.gnu.org/cgit/automake.git/commit/m4?id=d2ccbd7eb38d6a4277d6f42b994eb5a29b1edf29 This means that I just supplied variables that the user can override for the tags programs, rather than having the configure scripts actually check for them. I handle etags and ctags separately because the intl subdirectory has separate targets for them. This commit only affects the subdirectories that use handwritten Makefiles; the ones that use automake will have to wait until we update the version of automake used to be 1.16.4 or newer before they'll be fixed.

2021-11-29Fix PR 19089: Environment variable TMP may yield gcc: abortAndrew Pinski1-1/+15
Even though I cannot reproduce the ICE any more, this is still a bug. We check already to see if we can access the directory but never check to see if the path is actually a directory. This adds the check and now we reject the file as not usable as a tmp directory. OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions. libiberty/ChangeLog: * make-temp-file.c (try_dir): Check to see if the dir is actually a directory.

Darwin provides an implementation of sbrk, which is detected by the configuration process. However, it is deprecated which leads to build warnings. The malloc-based implementation is more suitable.

2021-08-30libiberty: Add support for demangling local D template declarationsIain Buclaw2-0/+43
The D language now allows multiple different template declarations in the same function that have the same mangled name. To make the mangled names unique, a fake parent in the form `__Sddd' is added to the symbol. This information is not important for the user, so the demangler now handles and ignores it. libiberty/ChangeLog: * d-demangle.c (dlang_identifier): Skip over fake parent manglings. * testsuite/d-demangle-expected: Add tests.

2021-05-06libiberty: add htab_eq_stringTom Tromey1-0/+7
The libiberty hash table includes a helper function for strings, but no equality function. Consequently, this equality function has been reimplemented a number of times in both the gcc and binutils-gdb source trees. This patch adds the function to the libiberty hash table, as a step toward the goal of removing all the copies. One change to gcc is included here. Normally I would have put this in the next patch, but gensupport.c used the most natural name for its reimplementation of this function, and this can't coexist with the extern function in libiberty. include * hashtab.h (htab_eq_string): Declare. libiberty * hashtab.c (htab_eq_string): New function. gcc * gensupport.c (htab_eq_string): Remove.

2021-05-04Fix libiberty link failures in LTO mode for MinGWEric Botcazou2-3/+3
The test for the presence of variables (really symbols) does not work when you add -Ox -flto to CFLAGS: for v in $vars; do AC_MSG_CHECKING([for $v]) AC_CACHE_VAL(libiberty_cv_var_$v, [AC_LINK_IFELSE([AC_LANG_PROGRAM([[int *p;]],[[extern int $v []; p = $v;]])], [eval "libiberty_cv_var_$v=yes"], [eval "libiberty_cv_var_$v=no"])]) if eval "test \"`echo '$libiberty_cv_var_'$v`\" = yes"; then AC_MSG_RESULT(yes) AC_DEFINE_UNQUOTED($n) else AC_MSG_RESULT(no) fi done because the assignment to 'p' is optimized away by LTO. This is visible on MinGW platforms in the form of a link failure for sys_siglist. There is another link failures for stpcpy: the symbol is both referenced by libiberty's pex-win32.c and provided by libiberty's stpcpy.c, so it needs to have a linkage to be resolved in LTO mode. libiberty/ * configure.ac: Make test for variables more robust. * configure: Regenerate. gcc/ * builtins.c (builtin_with_linkage_p): Return true for stp[n]cpy. * symtab.c (symtab_node::output_to_lto_symbol_table_p): Tidy up.

2021-03-30c++: Adjust mangling of __alignof__ [PR88115]Patrick Palka2-22/+29
r11-4926 made __alignof__ get mangled differently from alignof, encoding __alignof__ as a vendor extended operator. But this mangling is problematic for the reasons mentioned in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88115#c6. This patch changes our mangling of __alignof__ to instead use the new "vendor extended expression" syntax that's proposed in https://github.com/itanium-cxx-abi/cxx-abi/issues/112. Clang does the same thing already, so after this patch Clang and GCC agree about the mangling of __alignof__(type) and __alignof__(expr). gcc/cp/ChangeLog: PR c++/88115 * mangle.c (write_expression): Adjust the mangling of __alignof__. include/ChangeLog: PR c++/88115 * demangle.h (enum demangle_component_type): Add DEMANGLE_COMPONENT_VENDOR_EXPR. libiberty/ChangeLog: PR c++/88115 * cp-demangle.c (d_dump, d_make_comp, d_expression_1) (d_count_templates_scopes): Handle DEMANGLE_COMPONENT_VENDOR_EXPR.
