as go is concerned). the -d flag is now flipped; as on the mac, -d disables dynamic.
much remains to be improved to move the output closer to the gcc format.

* use new Make.$GOARCH files in gobuild.
* rename 6ar to arch-generic gopack.
* place objects in $GOROOT/pkg/$GOOS_$GOARCH
(makes cross-compiling easier, and no one
ever types these paths by hand anyway).

editing the firstp list was ineffective,
because follow rebuilds it from the textp list.
the symbols for dead code were being dropped
from the binary but the code was all still there.
text for fmt.Printf("hello, world\n") drops
from 143945 to 128650.

this allows gotest to find the locally built package when doing
make
gotest
without this option, one would have to say
make install
gotest
which kinda defeats the purpose
based on discussions with rsc.

store only the original import path string (+ .a)
if 6g resolves it to an archive file.
let 6l re-resolve the .a at link time.
this lets libraries build against an archive
in the current directory but get used
against an installed archive.

160 - 75 was just barely not enough for deferproc + morestack.
added enum names and bumped to 256 - 128.
added explanation.
changed a few mal() (garbage-collected) to
malloc()/free() (manually collected).

into gc directory, where it gets included as ../gc/ldbody
this is similar to the assemblers including ../cc/lexbody
and ../cc/macbody.
* hook go-specific loader code into 8l.
* make current 8.out.h and 6.out.h backward compatible
with plan 9's versions. i had added some constants in
the middle of enums and have now moved them to the end.
this keeps us from invalidating old .8 and .6 files.
not sure how much it really matters, but easy to do.

move darwin-amd64 specific code into runtime/darwin/amd64/

move rt0 into runtime.a instead of keeping a separate .6 file.

is not right if the .6 is only for data and
the init function.
instead of that, pick up everything and
let the dead code/data eliminator throw
away the parts that weren't useful.

unless given -d flag.
the resulting binary doesn't *use* any dynamic libraries,
it just has a reference to the dynamic linker and an
empty list of needed symbols and libraries.
this is enough to make 6.out binaries that can be run
under dtrace / dtruss.
