# 02e,28mar02,cym  don't perform POST_BUILD_RULE twice in rom targets
# 02d,31jan02,fmk  remove redirection operator to generate symTbl.c
# 02c,11dec01,rbl  get e.g. vxWorks_romCompress.hex image working
# 02b,07dec01,tpw  Remove HEX_HIGH_FLAGS and HEX_LOW_FLAGS, and fix proj %.hex
# 02a,12nov01,dat  added prj_default, fixes for gnu and diab projects

#		   expansion of '-l<ar>' to 'lib<ar>.a'
# 01v,25oct01,dat  Relocating tool specific macros
# 01u,22oct01,cym  replacing BOOT_OBJS with romInit.o and romStart.o for

# 01t,06aug01,mem  Added LD_LINK_LIBS and LD_LINK_PATH
# 01s,06apr00,dra  Added HEX_LOW_FLAGS and HEX_HIGH_FLAGS to support FRV
#                  (Venus) toolchain.
# 01r,31mar00,rsh  final merge es.tor2_0.mcore to tor2_0_0.es.coretools
# 01q,02mar00,rsh  add .hex$(MAP_EXT) suffix to BINHEX_OUTPUT_FILE rules.
# 01p,01mar00,rsh  adding rule to clean .hex related temp files for each rom
#                  based image and remove POST_BUILD_RULE definition.
# 01o,29feb00,rsh  adding definition of POST_BUILD_RULE to rm temporary
#                  out.tmp1 and out.tmp2 files.
# 01n,06jan00,dra updated for new .hex file generation.
# 01m,04mar99,sn  added machinery to handle large projects

# 01j,11nov98,sn  partially link using LD_PARTIAL
# 01i,11nov98,sn  munch -> orderCtors
# 01h,30oct98,yh  added deadweight removal hook.
# 01g,26oct98,ms  added EXTRA_MODULES. romInit.o etc now part of BOOT_OBJS.
# 01g,21apr99,bc  Alter BINXSYM command line for objcopy interface.
# 01f,26aug98,ms  added POST_BUILD_RULE. Link against COMPONENT_LIBS.
# 01e,07jul98,ms  added MAKE_SYM_CVT macro, added LDOUT_CONV to vxWorks.
# 01d,29jun98,ms  renamed vxWorks_downLoadable to just vxWorks.
# 01c,25jun98,ms  build rom* files is subdirectories. LDDEPS now comes first.
