I am getting the following build break on changeset 13662. I am
compiling on x86_64 SLES10 with gcc 4.1.0. Is there a fix for this?

Thanks,

Noone else is seeing this as far as I know. Are you sure this is due to a
recent changeset rather than something about your build environment? If the
former, working out the specific bad changeset will be useful.

I am getting this break from changeset 13642:480436ef6255 onwards.
13641: b97780b7080d builds successfully for me.

You'll have to drill into this a bit yourself I think. That changeset does
add a fair bit more assembly language to the rombios codebase (particularly
in 32bitgateway.c) but it doesn't look particularly different from the
existing assembly language in rombios.c. Clearly there *is* a difference
though -- perhaps you can narrow down which lines are causing the problem
and tinker with them a bit to see what's causing as86 to barf?

It's definitely odd: unlike gas I don't think there are that many different
versions of as86 to be causing weird differing build-environment behaviours.

The offending lines are from the macro DoUpCall in 32bitgateway.c and
macro POST_MEASURE in tcgbios.c

32bitgateway.c (line 410)
MACRO DoUpcall
mov bx, #?1 <====
jmp Upcall
MEND

Tcgbios.c (line 182)
ACRO POST_MEASURE
push word #0x000f
push #?2 <====
push word #0x000f
push #?1 <====
call _tcpa_measure_post
add sp, #8
MEND

as86 does not like the #? notation even though the man pages say that it
perfectly legal.

Any idea what's going on?

Thanks,
Aravindh

Not really. Fortunately the entire rombios is stuffed through cpp, so we can
use C macros instead, which also has other advantages (everyone knows the
syntax, parameters are named, etc).

bin86 / dev86 packages too old. 0.16.17 works ok. 0.16.0 doesn't.

Macro invocations have to bracket the arguments in older versions of as86.
This is now fixed in the staging tree so old versions of as86 will continue
to work.
