2020-05-14libiberty: Update D symbol demangling for latest ABI spec.Iain Buclaw3-261/+613
Some small improvements and clarifications have been done in the D ABI specification to remove all ambiguities found in the current grammar, this implementation now more closely resembles the spec, whilst maintaining compatibility with the old ABI. Three new rules have been added to the ABI. 1. Back references using 'Q', analogous to C++ substitutions, compresses repeated identifiers, types, and template symbol and value parameters. 2. Template aliases to externally mangled symbols are prefixed with 'X'. This includes any symbol that isn't extern(D), or has its name overriden with pragma(mangle). This fixes an ambiguity where it was not clear whether 'V' was an encoded calling convention, or the next template value parameter. 3. Alias parameters, templates, and tuple symbols no longer encode the symbol length of its subpart. Tuples are now terminated with 'Z'. This fixes another ambiguity where the first character of the mangled name can be a digit as well, so the demangler had to figure out where to split the two adjacent numbers by trying out each combination. libiberty/ChangeLog: * d-demangle.c (enum dlang_symbol_kinds): Remove enum. (struct dlang_info): New struct (dlang_decode_backref): New function. (dlang_backref): New function. (dlang_symbol_backref): New function. (dlang_type_backref): New function.

2020-02-12Use a non-empty test program to test ability to link.Sandra Loosemore2-2/+9
On bare-metal targets, I/O support is typically provided by a BSP and requires a linker script and/or hosting library to be specified on the linker command line. Linking an empty program with the default linker script may succeed, however, which confuses libstdc++ configuration when programs that probe for the presence of various I/O features fail with link errors. 2020-02-12 Sandra Loosemore <sandra@codesourcery.com> PR libstdc++/79193 PR libstdc++/88999 config/ * no-executables.m4: Use a non-empty program to test for linker support. libgcc/ * configure: Regenerated. libgfortran/ * configure: Regenerated. libiberty/ * configure: Regenerated. libitm/ * configure: Regenerated. libobjc/ * configure: Regenerated. libquadmath/ * configure: Regenerated. libssp/ * configure: Regenerated. libstdc++v-3/ * configure: Regenerated.

2019-02-12Fix splay tree KEY leak detected in GDB test gdb.base/macscp.expPhilippe Waroquiers2-3/+16
When a node is removed from a splay tree, the splay tree was not using the function splay_tree_delete_key_fn to release the key. This was causing a leak, fixed by Tom Tromey. This patch fixes another key leak, that happens when a key equal to a key already present is inserted. In such a case, we have to release the old KEY. Note that this is based on the assumption that the caller always allocates a new KEY when doing an insert. Also, clarify the documentation about when the release functions are called. 2019-02-11 Philippe Waroquiers <philippe.waroquiers@skynet.be> * splay-tree.h (splay_tree_delete_key_fn): Update comment.

Philippe Waroquiers noticed a memory leak in gdb, which he tracked down to a bug in splay-tree. splay_tree_remove does not call the `delete_key' function when it removes the old node; but it should. I looked at every splay tree in GCC and there is only one that passes a non-NULL delete function -- the one in lto.c. That file does not call splay_tree_remove. So, I think this is safe to check in. I re-ran the LTO tests to double check. libiberty/ * splay-tree.c (splay_tree_remove): Delete the key if necessary. From-SVN: r268116
