47# Ugh, this is a gross hack.  Our assembly routines uses lots of defines
48# to simplify variable access.  All these defines work fine for amd64
49# compiles because when compiling for amd64 we use the GNU assembler,
50# gas.  For 32-bit code we use the Sun assembler, as.  Unfortunatly
51# as does not handle certian constructs that gas does.  So rather than
52# make our code less readable, we'll just use gas to compile our 32-bit
53# code as well.

58# Note that the architecture specific makefiles MUST update DYNFLAGS to
59# explicily specify an interpreter for the brand emulation library.
60# Normally this would be the native linker, /.SUNWnative/usr/lib/ld.so.1
61# or /.SUNWnative/usr/lib/64/ld.so.1.
62#
63# Note that we make sure to link our brand emulation library
64# libmapmalloc.  This is required because in most cases there will be two
65# copies of libc in the same process and we don't want them to fight over
66# the heap.  So for our brand library we link against libmapmalloc so that
67# if we (our or copy of libc) try to allocate any memory it will be done
68# via mmap() instead of brk().
69#
70# XXX: Note that we also set the runtime path for the emulation library to
71# point into /.SUNWnative/.  This ensures that our brand library get's the
72# native versions of any libraries it needs.  Unfortunatly this is a total
73# hack since it doesn't work for suid binaries.  What we really need to do
74# is enhance the linker so that when it's running on a brand linkmap it
75# looks for all libraries in the brands "native" directory (for both
76# regular and suid binaries).
