# abilist-pattern configurability

|
|
00db10 |
# This patch creates implicit rules to match the abifiles if
|
|
|
00db10 |
# abilist-pattern is defined in the architecture Makefile. This allows
|
|
|
00db10 |
# machine specific Makefiles to define different abifiles names
|
|
|
00db10 |
# (for instance *-le.abilist for powerpc64le).
