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. 41 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. 107 108# 109# Common Macro definitions 110# 111VAR_CPPFLAGS= 112VAR_XFFLAG= -xF=%all 113 114VAR_LINTFLAGS64= -Xarch=$(MACH64:sparcv9=v9) 115VAR_I386_ARCH= intel 116 117VAR_PLAT_sparc= sparc 118VAR_PLAT_i386= intel/ia32 119VAR_PLAT_amd64= intel/amd64 120 121VAR_POUND_1= 122VAR_POUND_2= $(POUND_SIGN) 123VAR_POUND_3= $(POUND_SIGN) 124 125# 126# VAR_AVLDIR - directory to find avl.c in. 127# 128# The avl.c file is under usr/src/common/avl in Solaris 10 (and later), 129# but in earlier releases it is not present (problem to be solved). 130# 131# The avl.h and avl_impl.h files are under usr/src/uts/common/sys in 132# Solaris 10 (and later).
