27 # Note: libast headers are generated by the AST build system outside OS/Net
28 # (and then copied here) and depend on the architecture (e.g. "i386", "amd64",
29 # "sparc", "sparcv9" etc. ...), we later merge them into one unified file
32 ROOTHDRDIR= $(ROOT)/usr/include/ast
34 # Define the symbol used to distinguish between 32bit and 64bit parts of the
35 # include file. We cannot use |_LP64| here because not every compiler (like
36 # Studio 10/11/12) sets it by default (this doesn't harm because the AST
37 # includes are OS- and platform-specific anyway) and we can't rely on the
38 # system includes like <sys/isa_defs.h> because "/usr/bin/diff -D<symbol>"
39 # adds the "#ifdef <symbol>" before any other content and "injecting" an
40 # "#include <sys/isa_defs.h>" will alter the behaviour of the AST code
41 # in unpredictable ways (e.g. the resulting code will not longer work).
42 # Sun-Bug #6524070 ("RFE: Please set |_LP64| for 64bit platforms by default
43 # (like gcc does)") has been filed against the Sun Studio compiler as RFE
44 # to set |_LP64| for 64bit targets.
45 # (INTEL_BLD is '#' for a Sparc build and SPARC_BLD is '#' for an Intel build)

49 # We use a custom install sequence here to unify 32bit and 64bit AST includes
50 # since we can only ship one set of includes. Therefore we use
51 # "/usr/bin/diff -D <64bit>" (and for some exceptions a manual path) to
52 # generate an unified version of the include files (and add a boilerplate text
53 # which explains the interface stability status).
