# The link-editor related source files and Makefile files are normally unified

# across all presently maintained release gates. However, some of the compiler

# pre-processor flags, linker flags are different among the releases. This

# file is used to specify such flags.

#

# This file is included by the ./Makefile.com.

#

# This file should be the only file which is different among the presently

# maintained release workspaces and the files that generate the link-editors

# and related tools.

#

# CPPFEATUREMACROS provides for selectively turning on/off features within the

# build of ld.so.1 and liblddbg.so.

#

# Current values for ld.so.1 are:

#

# LD_BREADTH_DISABLED

# per bug id 4313765, the LD_BREADTH= environment variable is no

# longer checked. However, on older releases we still want to

# keep this check valid.

#

# EXPAND_RELATIVE

# per bug id 4336980 (and 4336878), relative path expansion is

# insured at process startup. This implementation can come at

# some cost unless the corresponding getcwd() implementation from

# libc_pic.a is also available. On older releases defer any

# relative pathname expansion until it is required.

#

# ISSOLOAD_BASENAME_DISABLED

# The bugfix for bug#4469400 updates the logic by which

# shared objects are loaded into memory (and makes it

# more precise). However - this update to logic can

# mess up the loading of objects which have a dependency

# on both '/usr/lib/lwp/libthread.so.1' and

# '/usr/lib/libthread.so.1'. The error that occurs is that

# both libraries are loaded into memory - which doesn't

# work out very well. This fix re-enables the `loose'

# logic which was implemented on older releases to avoid

# exposing problems with multiple libthreads. Since Soliars9

# again only has one libthread - we can use the more precise

# logic.

#

# SIEBEL_DISABLE

# Prior to Solaris 10, bug fixes 4651709 and 4651493 were deter-

# mined to be inappropriate for patch releases as they broke the

# Siebel server. Siebel agree to fix their code in preparation

# for these changes to become default in Solaris 10. Users who

# want these fixes in patch releases can set LD__FIX__1.

#

#

# Current value for liblddbg.so is:

#

# DEMANGLE

# enable use of the "demangle" debug token. Old versions of the

# demangle library libdemangle.so.1 used an excessive amount of

# stack space that could cause debugging a threaded application

# (with say LD_DEBUG=symbols,demangle) to segv because of an

# exhausted stack. See 4376081. DEMANGLE should not be enabled

# for patch builds.

#

# Note that demangling support within liblddbg.so.1 is always

# available, as tools such as elfdump(1) and pvs(1) may call this

# directly. These tools aren't threaded, and thus don't expose

# the problems raised by enabling ld.so.1's debugging output.

#

#

# Although most files are unified among on10-gate, on81-patch, and on28-patch

# gates, some files in libld and rtld need to use #ifdef to distinguish between

# the patch release, and for the packages targeting to the pre-libc/libthread

# unified environment. These values are available for CPPFLAGS:

#

# SGS_PRE_UNIFIED_PROCESS

#

# is set if the target release is for pre-libc/libthread unified

# environment. This is used for rtld and crle.
