Hopefully, it can be enabled by default 893N/A# once the .debuginfo size issues are worked out. 893N/A# Default OBJCOPY comes from the SUNWbinutils package: 1319N/A # BFD: stKPaiop: Not enough room for program headers, try linking with -N 893N/A # BFD: stKPaiop: Not enough room for program headers, try linking with -N 893N/A # BFD: stKPaiop: Not enough room for program headers, try linking with -N 893N/A # disable .debuginfo support by setting ALT_OBJCOPY to a non-existent path 893N/A# The setting of OBJCOPY above enables the JDK build to import 893N/A# .debuginfo files from the HotSpot build. However, adding FDS 893N/A# support to the JDK build will occur in phases so a different 893N/A# make variable is used to indicate that a particular library 893N/A echo >&2 "INFO: no objcopy cmd found so cannot create .debuginfo files.") 893N/A echo >&2 "INFO: $(OBJCOPY) cmd found so will create .debuginfo files.") 893N/A # Library stripping policies for .debuginfo configs: 893N/A # all_strip - strips everything from the library 893N/A # min_strip - strips most stuff from the library; leaves minimum symbols 893N/A # no_strip - does not strip the library at all 893N/A # Oracle security policy requires "all_strip". A waiver was granted on 893N/A # 2011.09.01 that permits using "min_strip" in the Java JDK and Java JRE. 893N/A# Java default optimization (-x04/-O2) etc. Applies to the VM. 893N/A# If -Xa is in CFLAGS_COMMON it will end up ahead of $(CC_OPT) for the 893N/A# optimized build, and that ordering of the flags completely freaks 893N/A# out cc. Hence, -Xa is instead in each CFLAGS variant. 893N/A# The more unusual options to the Sun C compiler: 893N/A# -v Stricter type checking, more error checking 893N/A# (To turn ALL warnings into fatals, use -errwarn=%all) 893N/A# -xstrconst Place string literals and constants in read-only area 893N/A# (means you can't write on your string literals) 893N/A# -xs Force debug information (stabs) into the .so or a.out 893N/A# .o files needing to be around, but at a space cost) 893N/A# -g & -O If you add the -g option to the optimized compiles 893N/A# you will get better stack retraces, the code is 2748N/A# still optimized. This includes a space cost too. 893N/A# -xc99=%none Do NOT allow for c99 extensions to be used. 893N/A# e.g. declarations must precede statements 893N/A# -xCC Allow the C++ style of comments in C: // 893N/A# Required with many of the source files. 893N/A# -mt Assume multi-threaded (important) 893N/A# The more unusual options to the Sun C compiler: 893N/A# +w Print more warnings 893N/A# Debug flag for C and C++ compiler 893N/A# Turn off -g if we are doing tcov build 893N/A# FASTDEBUG: Optimize the -g builds, gives us a faster debug java 893N/A# If true adds -O to the debug compiles. This allows for any assert 893N/A# tests to remain and debug checking. The resulting code is faster 893N/A# but less debuggable. Stack traces are still valid, although only 893N/A# approximate line numbers are given. Printing of local variables 893N/A# during a debugging session is not possible, but stepping and 893N/A# printing of global or static variables should be possible. 893N/A# Do not allow C99 language features like declarations in code etc. 893N/A# Allow C++ comments in C code 893N/A# Show error message tags on errors 893N/A# Required C compiler flags 1319N/A# Maximum warnings all the time 893N/A# Assume MT behavior all the time (important) 893N/A# Assume no C++ exceptions are used 893N/A# For C++, these options tell it to assume nothing about locating libraries 893N/A# either at compile time, or at runtime. Use of these options will likely 893N/A# require the use of -L and -R options to indicate where libraries will 893N/A# be found at compile time (-L) and at runtime (-R). 893N/A# The /usr/lib location comes for free, so no need to specify that one. 893N/A# Note: C is much simplier and there is no need for these options. This 893N/A# is mostly needed to avoid dependencies on libraries in the 893N/A# Compiler install area, also see LIBCXX and LIBM. 893N/A# Treat compiler warnings as errors, if requested 893N/A# Add -xstrconst to the library compiles. This forces all string 893N/A# literals into the read-only data section, which prevents them from 893N/A# being written to and increases the runtime pages shared on the system. 893N/A# Source browser database 893N/A# If defined adds -xsb to compiles and creates a 893N/A# source browsing database during compilation. 893N/A# -Xa ANSI C plus K&R, favor ANSI rules 893N/A# -fd report on old style func defs 893N/A# -errchk=structarg report on 64bit struct args by value 893N/A# -errchk=longptr64 report on 64bit to 32bit issues (ignores casts) 893N/A# -errchk=parentheses report on suggested use of extra parens 893N/A# -v suppress unused args 893N/A# -x suppress unused externs 893N/A# -errfmt=simple use one line errors with position info 893N/A# The -W0,-noglobal tells the compiler to NOT generate mangled global 893N/A# ELF data symbols for file local static data. 3899N/A# This can break fix&continue, but we'd rather do the same compilations 893N/A# for deliverable bits as we do for non-deliverable bits 893N/A# Tell the compilers to never generate globalized names, all the time. 893N/A# If we have a specific arch value to use, add it 893N/A# uncomment the following to build with PERTURBALOT set 893N/A# OTHER_CFLAGS += -DPERTURBALOT 893N/A # The macro _LITTLE_ENDIAN needs to be defined the same to avoid the 893N/A # Sun C compiler warning message: warning: macro redefined: _LITTLE_ENDIAN 893N/A # Note: -Dmacro is the same as #define macro 1 893N/A # -Dmacro= is the same as #define macro 3471N/A # Turn off a superfluous compiler error message on Intel 3471N/A# Java memory management is based on memory mapping by default, but a 893N/A# -L paths for finding and -ljava 893N/A# We never really want the incremental linker, ever 893N/A# The -xildoff option tells Sun's compilers to NOT use incremental linker 893N/A # Libraries need to locate other libraries at runtime, and you can tell 893N/A # a library where to look by way of the dynamic runpaths (RPATH or RUNPATH) 893N/A # buried inside the .so. The $ORIGIN says to look relative to where 893N/A # the library itself is and it can be followed with relative paths from 893N/A # that.
