# DP: There are two exception mechanisms to choose from: zero-cost and
# DP: setjump/longjump.  The Ada run-time library uses either of them
# DP: but not both.  Build both versions of the run-time library.

# This patch changes the way the upstream Makefiles build the run-time
# library.  Before the patch: libada/Makefile calls gcc/ada/Makefile,
# which builds the "rts" subdirectory containing symbolic links to
# most source files, and modified copies of a few source files (to
# take target dependencies into account, and also to select the
# exception handling mechanism in system.ads).  Then, gcc/ada/Makefile
# calls itself recursively but in the "rts" subdirectory and builds
# libgnat.a and libgnarl.a (and a couple other libraries:
# libgccprefix.a, libgmem.a).  Upon return from this recursive call,
# it deletes the source and object files from "rts", reconstructs the
# source files, and builds libgnat.so and libgnarl.so by calling
# itself recursively a second time in the "rts" directory.

# Furthermore, gcc/ada/Makefile disables parallel makes, so building
# the static and then shared versions of the RTS is entirely
# sequential even on SMP systems.

# As a consequence of the above, building the SJLJ version of the
# library would overwrite the ZCX version.  Thus it is necessary to
# manually save the previous version of the library before building the
# second one.

# After the patch: libada/Makefile calls gcc/ada/Makefile, which
# builds the source directory (named gnatlib-sources instead of rts),
# containing the symbolic links and target-dependent files.

# In a second step, libada/Makefile calls gcc/ada/Makefile again to
# build the targets gnatlib-shared-zcx, gnatlib-static-zcx and
# gnatlib-static-sjlj (we could also build gnatlib-shared-sjlj, but
# that triggers compiler errors on PowerPC).

# Each of these three targets copies the source directory "rts" into a
# new directory named rts-shared-zcx, rts-static-zcx or
# rts-static-sjlj.  In the new directory, they change the value of
# System.ZCX_By_Default, and then they call gcc/ada/Makefile
# recursively in the new directory to build the library.

# gcc/ada/Makefile.in has a .NOTPARALLEL directive preventing it from
# launching commands in parallel.  However, libada/Makefile has no
# such directive and can invoke up to three instances of
# gcc/ada/Makefile.in in parallel.  This is okay because each of them
# runs in a different directory.

# This patch also updates libgnat{vsn,prj}/Makefile and
# gnattools/Makefile to look for the shared ZCX version of the library
# in the appropriate directory, rather than just "rts", and updates
# the "make install" and binary targets as well.
