29# The link-editor related source files and Makefile files are normally unified
30# across all presently maintained release gates.  However, some of the compiler
31# pre-processor flags, linker flags are different among the releases.  This
32# file is used to specify such flags. 
33# 
34# This file is included by ./Makefile.com, but may also be included directly
35# in the case where the utility is relying on the contents of 
36# ../../Makefile.com.
37# 
38# This file should be the only file which is different among the presently
39# maintained release workspaces and the files that generate the link-editors
40# and related tools.

42#
43# CPPFEATUREMACROS provides for selectively turning on/off features within the
44# build of ld.so.1 and liblddbg.so.
45#
46# Current values for ld.so.1 are:
47#
48#	LD_BREADTH_DISABLED
49#		per bug id 4313765, the LD_BREADTH= environment variable is no
50#		longer checked.  However, on older releases we still want to
51#		keep this check valid.
52#
53#	EXPAND_RELATIVE
54#		per bug id 4336980 (and 4336878), relative path expansion is
55#		insured at process startup.  This implementation can come at
56#		some cost unless the corresponding getcwd() implementation from
57#		libc_pic.a is also available.  On older releases defer any
58#		relative pathname expansion until it is required.
59#
60#	ISSOLOAD_BASENAME_DISABLED
61#		The bugfix for bug#4469400 updates the logic by which
62#		shared objects are loaded into memory (and makes it
63#		more precise).  However - this update to logic can
64#		mess up the loading of objects which have a dependency
65#		on both '/usr/lib/lwp/libthread.so.1' and
66#		'/usr/lib/libthread.so.1'.  The error that occurs is that
67#		both libraries are loaded into memory - which doesn't
68#		work out very well.  This fix re-enables the `loose'
69#		logic which was implemented on older releases to avoid
70#		exposing problems with multiple libthreads.  Since Soliars9
71#		again only has one libthread - we can use the more precise
72#		logic.
73#
74#	SIEBEL_DISABLE
75#		Prior to Solaris 10, bug fixes 4651709 and 4651493 were deter-
76#		mined to be inappropriate for patch releases as they broke the
77#		Siebel server.  Siebel agree to fix their code in preparation
78#		for these changes to become default in Solaris 10.  Users who
79#		want these fixes in patch releases can set LD__FIX__1.
80#
81#
82# Current value for liblddbg.so is:
83#
84#	DEMANGLE
85#		enable use of the "demangle" debug token.  Old versions of the
86#		demangle library libdemangle.so.1 used an excessive amount of
87#		stack space that could cause debugging a threaded application
88#		(with say LD_DEBUG=symbols,demangle) to segv because of an
89#		exhausted stack.  See 4376081.  DEMANGLE should not be enabled
90#		for patch builds.
91#
92#		Note that demangling support within liblddbg.so.1 is always
93#		available, as tools such as elfdump(1) and pvs(1) may call this
94#		directly.  These tools aren't threaded, and thus don't expose
95#		the problems raised by enabling ld.so.1's debugging output.
96#
97#
98# Although most files are unified among on10-gate, on81-patch, and on28-patch
99# gates, some files in libld and rtld need to use #ifdef to distinguish between
100# the patch release, and for the packages targeting to the pre-libc/libthread
101# unified environment.  These values are available for CPPFLAGS:
102#	
103#	SGS_PRE_UNIFIED_PROCESS
104#
105#		is set if the target release is for pre-libc/libthread unified
106#		environment. This is used for rtld and crle.
