/* Create a fundamental C type using default reasonable for the current

|
|
|
|
|
|
|
|
|
|
Some object/debugging file formats (DWARF version 1, COFF, etc) do not
|
|
|
|
|
define fundamental types such as "int" or "double". Others (stabs or
|
|
|
|
|
DWARF version 2, etc) do define fundamental types. For the formats which
|
|
|
|
|
don't provide fundamental types, gdb can create such types using this
|
|
|
|
|
function.
|
|
|
|
|
|
|

|
|
FIXME: Some compilers distinguish explicitly signed integral types
|
|
|
|
|
(signed short, signed int, signed long) from "regular" integral types
|
|
|
|
|
(short, int, long) in the debugging information. There is some dis-
|
|
|
|
|
agreement as to how useful this feature is. In particular, gcc does
|
|
|
|
|
not support this. Also, only some debugging formats allow the
|
|
|
|
|
distinction to be passed on to a debugger. For now, we always just
|
|
|
|
|
use "short", "int", or "long" as the type name, for both the implicit
|
|
|
|
|
and explicitly signed types. This also makes life easier for the
|
|
|
|
|
gdb test suite since we don't have to account for the differences
|
|
|
|
|
in output depending upon what the compiler and debugging format
|
|
|
|
|
support. We will probably have to re-examine the issue when gdb
|
2005-04-19 13:58:24 +08:00

/* When we find that lexptr (the global var defined in parse.c) is

pointing at a macro invocation, we expand the invocation, and call
|
|

scan_macro_expansion to save the old lexptr here and point lexptr
|
|
|
|
|
into the expanded text. When we reach the end of that, we call

|

end_macro_expansion to pop back to the value we saved here. The

macro expansion code promises to return only fully-expanded text,

so we don't need to "push" more than one level.

This is disgusting, of course. It would be cleaner to do all macro

expansion beforehand, and then hand that to lexptr. But we don't

really know where the expression ends. Remember, in a command like

(gdb) break *ADDRESS if CONDITION

we evaluate ADDRESS in the scope of the current frame, but we

evaluate CONDITION in the scope of the breakpoint's location. So

it's simply wrong to try to macro-expand the whole thing at once. */
