2021-09-01libiberty, configure, Darwin: Avoid detecting deprecated sbrk.Iain Sandoe3-25/+35
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. This patch removes sbrk from the functions searched for Darwin. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> libiberty/ChangeLog: * configure: Regenerate. * configure.ac: Do not search for sbrk on Darwin. * xmalloc.c: Do not declare sbrk unless it has been found by configure.

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.
2021-08-30libiberty: Add support for demangling D function literals as template value ↵Iain Buclaw2-13/+31
parameters The D language now allows instantiating templates using struct literals that have function literal fields as a value argument. libiberty/ChangeLog: * d-demangle.c (dlang_parse_arrayliteral): Add 'info' parameter. (dlang_parse_assocarray): Likewise. (dlang_parse_structlit): Likewise. (dlang_value): Likewise. Handle function literal symbols. (dlang_template_args): Pass 'info' to dlang_value. * testsuite/d-demangle-expected: Add new test.
2021-08-30libiberty: Add support for D `typeof(*null)' typesIain Buclaw2-3/+15
The D language has a new bottom type `typeof(*null)'. Null types were also incorrectly being demangled as `none', this has been fixed to be `typeof(null)'. libiberty/ChangeLog: * d-demangle.c (dlang_attributes): Handle typeof(*null). (dlang_type): Likewise. Demangle 'n' as typeof(null). * testsuite/d-demangle-expected: Update tests.

2021-08-18libiberty, Darwin : Fix simple-object LTO table for cross-endian case.Iain Sandoe1-0/+5
We encapsulate streamed IR in three special sections with a table that describes their entries. The table is expected to be written with native endianness for the target, but for cross-endian cross- compilation the swapping was omitted. Fixed thus. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> libiberty/ChangeLog: * simple-object-mach-o.c (simple_object_mach_o_write_segment): Arrange to swap the LTO index tables where needed.

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.

2020-12-21c++: Fix demangling of <unresolved-name>Jason Merrill3-22/+72
The ABI for unresolved scoped names on the RHS of . and -> used to be sr <type> <unqualified-id> That changed years ago to something more complex, but G++ was never updated. This change was particularly incompatible for simple qualified-ids like A::x, which were previously mangled as sr1A1x, and now sr1AE1x. This obviously makes life hard for demanglers, which can't know whether to consume that E or not. To work around this, we now try demangling with the newer ABI, and if that fails and we saw an "sr", try again with the older ABI. libiberty/ChangeLog: PR c++/67343 * cp-demangle.h (struct d_info): Add unresolved_name_state. * cp-demangle.c (d_prefix): Add subst parm.
