31# The link-editor related source files and Makefile files
32# are unified for on10-gate, on{81,28,998}-patch gates.
33# However, some of the compiler pre-processor flags, linker flags
34# are different among the releases. This file is used to
35# specify such flags.
36#
37# This file is included by the ./Makefile.com.
38#
39# This file should be the only file which is different
40# among /ws/{on10-gate,on{81,28,998}-patch} workspaces
41# among the files which generate link-editors and related tools.

43#
44# CPPFEATUREMACROS provides for selectively turning on/off features within the
45# build of ld.so.1 and liblddbg.so.
46#
47# Current values for ld.so.1 are:
48#
49#	LD_BREADTH_DISABLED
50#		per bug id 4313765, the LD_BREADTH= environment variable is no
51#		longer checked.  However, on older releases we still want to
52#		keep this check valid.
53#
54#	EXPAND_RELATIVE
55#		per bug id 4336980 (and 4336878), relative path expansion is
56#		insured at process startup.  This implementation can come at
57#		some cost unless the corresponding getcwd() implementation from
58#		libc_pic.a is also available.  On older releases defer any
59#		relative pathname expansion until it is required.
60#
61#	ISSOLOAD_BASENAME_DISABLED
62#		The bugfix for bug#4469400 updates the logic by which
63#		shared objects are loaded into memory (and makes it
64#		more precise).  However - this update to logic can
65#		mess up the loading of objects which have a dependency
66#		on both '/usr/lib/lwp/libthread.so.1' and
67#		'/usr/lib/libthread.so.1'.  The error that occurs is that
68#		both libraries are loaded into memory - which doesn't
69#		work out very well.  This fix re-enables the `loose'
70#		logic which was implemented on older releases to avoid
71#		exposing problems with multiple libthreads.  Since Soliars9
72#		again only has one libthread - we can use the more precise
73#		logic.
74#
75#	SIEBEL_DISABLE
76#		Prior to Solaris 10, bug fixes 4651709 and 4651493 were deter-
77#		mined to be inappropriate for patch releases as they broke the
78#		Siebel server.  Siebel agree to fix their code in preparation
79#		for these changes to become default in Solaris 10.  Users who
80#		want these fixes in patch releases can set LD__FIX__1.
81#
82#
83# Current value for liblddbg.so is:
84#
85#	DEMANGLE
86#		enable use of the "demangle" debug token.  Old versions of the
87#		demangle library libdemangle.so.1 used an excessive amount of
88#		stack space that could cause debugging a threaded application
89#		(with say LD_DEBUG=symbols,demangle) to segv because of an
90#		exhausted stack.  See 4376081.  DEMANGLE should not be enabled
91#		for patch builds.
92#
93#		Note that demangling support within liblddbg.so.1 is always
94#		available, as tools such as elfdump(1) and pvs(1) may call this
95#		directly.  These tools aren't threaded, and thus don't expose
96#		the problems raised by enabling ld.so.1's debugging output.
97#
98#
99# Although most files are unified among on10-gate, on81-patch, and on28-patch
100# gates, some files in libld and rtld need to use #ifdef to distinguish between
101# the patch release, and for the packages targeting to the pre-libc/libthread
102# unified environment.  These values are available for CPPFLAGS:
103#
104#	SGS_PRE_UNIFIED_PROCESS
105#
106#		is set if the target release is for pre-libc/libthread unified
107#		environment. This is used for rtld and crle.
