Re: [Freedos-kernel] PATCH: sys fix
Hi Bart, thanks for making the patch much shorter, very commitable now :-) Why did our old code do that complex put bp at [bp+2] thing? And what does the cpm_error jump decision now inverted patch mean?

2009/5/1 Eric Auer e.a...@jpberlin.de: Why did our old code do that complex put bp at [bp+2] thing? I don't know; it is old code from Pat Villani. Perhaps it wanted to do an extra pop bp from that place but bp was already set to sp so that would be wrong too. -pushbp ; trash old return address -mov bp,sp -xchgbp,[2+bp] -pop bp Bart -- Register Now Save for Velocity, the Web Performance Operations Conference from O'Reilly Media.
