2013-03-12Allow 'thread' to be used as a variable name in expressions.Paul N. Hilfinger7-11/+176
GDB treats the identifiers 'if', 'thread', and 'task' unconditionally as expression delimiters in Ada mode, which is correct for 'if' and 'task', but wrong for 'thread' in cases such as print thread Borrowing from c-exp.y, we observe that 'thread' must be followed by numerals, whereas identifiers never are and treat them as delimiters only in that case. In the process, the current also refactors and incidentally fixes the code for rewinding the input to before the delimiting tokens. For example, the code watch expr if i > 2 fails because the input is only rewound to just before the 'i', leaving the 'if' as part of the expression (and thus making the rest look like trailing junk rather than a conditional clause). gdb/ChangeLog: * ada-lex.l (rules): Only recognize 'thread' as a delimiter when followed by numerals, as for c-exp.y. Use new rewind_to_char function to rewind the input for expression-delimiting tokens. (rewind_to_char): New function. gdb/testsuite/ChangeLog: * gdb.ada/expr_delims.exp: New file. * gdb.ada/expr_delims/foo.adb: New file. * gdb.ada/expr_delims/pck.ads: New file. * gdb.ada/expr_delims/pck.adb: New file.

2013-03-11Avoid invalid pointer to pointer conversions.Pedro Alves3-20/+35
Casts between 'char **' <-> 'unsigned char **' and 'char **' <-> const char **' are actually invalid: http://gcc.gnu.org/ml/gcc-help/2013-03/msg00118.html In a nutshell, char (and variants) can alias anything, but pointers to chars get no special treatment (cf. C99/N1256, 6.5/7). Turns out older gcc's actually warn/complain on these constructs, though newer one's don't: http://sourceware.org/ml/gdb-patches/2013-03/msg00429.html http://sourceware.org/ml/gdb-patches/2013-03/msg00430.html This patch fixes the cases I added last week. It also fixes one other preexisting case in charset.c, though it seems even older gccs don't complain of char * <-> const char * aliasing. Tested on x86_64 Fedora 17. gdb/ 2013-03-11 Pedro Alves <palves@redhat.com> * charset.c (convert_between_encodings): Don't cast between different pointer to pointer types. Instead, make the 'inp' local be of the type iconv expects. (wchar_iterate): Don't cast between different pointer to pointer types. Instead, use new pointer local of the type iconv expects. * target.c (target_read_stralloc, target_fileio_read_stralloc): Add new local of type char pointer, and use it to get a char/string view of the byte buffer, instead of casting between pointer to pointer types.
