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 the ./Makefile.com.
35# 
36# This file should be the only file which is different among the presently
37# maintained release workspaces and the files that generate the link-editors
38# and related tools.

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