|
We need this expand-one-token-at-a-time interface in order to
|
|
accommodate GDB's C expression parser, which may not consume the
|
|
entire string. When the user enters a command like
|
|
|
|
(gdb) break *func+20 if x == 5
|
|
|
|
the parser is expected to consume `func+20', and then stop when it
|
|
sees the "if". But of course, "if" appearing in a character string
|
|
or as part of a larger identifier doesn't count. So you pretty
|
|
much have to do tokenization to find the end of the string that
|
|
needs to be macro-expanded. Our C/C++ tokenizer isn't really
|
|
designed to be called by anything but the yacc parser engine. */
