Jeff,
This adds a child_xfer_partial method to "inftarg.c". I've included a
hook vis:
+#if 0
+ case TARGET_OBJECT_UNWIND_TABLE:
+#ifndef NATIVE_XFER_UNWIND_TABLE
+#define
NATIVE_XFER_UNWIND_TABLE(OPS,OBJECT,ANNEX,WRITEBUF,READBUF,OFFSET,LEN)
(-1)
+#endif
+ return NATIVE_XFER_UNWIND_TABLE (ops, object, annex, writebuf,
+ readbuf, offset, len);
+#endif
so that, in theory, all you need do is define that in the linux specific
nm-*.h file.
I think this will make plugging in additional xfer methods easier. How
does it look?
I like it because it means I only have to provide the particular functionality
instead of overriding the whole function which could be dangerous if other
changes were made to the default_xfer_partial routine.
Anyone else?
Andrew
PS: You'll notice that it also contains lurking code to add support for
an auxv transfer.
PPS: Note that I need to better test it.
