# this is the SunOS jdk builder
#
# it will attempt to download, patch, and build any jdk tag, and do so for
# SPARC and x86, and for illumos and Solaris 11.4
#
# will also function on SPARC/Linux (specifically debian-sparc) to
# validate the SPARC port on a regularly supported OS, although this
# script need to be called explicitly via bash, as the default sh of
# dash won't work
#
# it is dependent on the "jdk-sunos-patches" repository, which holds
# all the patches for each tag
#

#
# this is where the repositories are rooted

# Usage: dobuild [flags] tag
#
# valid flags are:
# -d [download]
# -p [patch]
# -P [patch, remove existing copy first]
# -b [build]
# -B [build, remove existing copy first]
# -t [enable tests]
# -T type [build type - release, fastdebug, slowdebug, optimized]
# -C flags [extra flags to pass to configure]
# -c cpu [override cpu (sparc or x86)]
# -o os [override os (illumos or Solaris)]
# -f feature [enable given patch feature]
# -i [install]
# -e [export]
#
# previous steps will be executed if necessary, but the expected workflow
# is to first download, then repeat the patch step until clean, then run
# the build step until that's clean

-c cpu  override cpu (sparc or x86)
-o os  override os (illumos or Solaris)
-C flags  extra flags to pass to configure
-f feature  enable given patch feature
-i  link the given jdk into the list of available instances
