Re: ld -r breakage


Hi Alan,

: 
: Hmm.  We started with (1)
: config.text_read_only true => make .text read only
: config.text_read_only false => don't change .text attributes
: 
: This was buggy because "ld -N" needs to mark .text read/write
: 
: Then we went to (2)
: config.text_read_only true => make .text read only
: config.text_read_only false => make .text read/write
: 
: This is again incorrect because "ld -r" cleared config.text_read_only so
: as to leave the section attributes unchanged as per (1).  Under (2), we
: get a read/write .text section.
: 
: I suggested testing link_info.relocatable so that "ld -r" would again
: leave the section attributes unchanged.  It's true that the patch I
: submitted should have removed the unnecessary clearing of
: config.text_read_only for `-r' (and `-Ur').
: 
: Now you seem to be saying (3)
: config.text_read_only true => don't change .text attributes
: config.text_read_only false => make .text read/write
: 
: ??

OK - sorry for all this confusion.  I actually agree with scenario (2)
above, although I obviously did not express myself clearly.  If you
would care to resubmit your patch (with the fix to -r and -Ur that you
mention above) then I will be happy yto approve it.

Cheers
	Nick
