# TARGET_STAGE_N template: This defines how target artifacts are built

|
# for all stage/target architecture combinations. The arguments:
|
|
# $(1) is the stage
|
|
# $(2) is the target triple
|
|
# $(3) is the host triple
|

|
# If you are making non-backwards compatible changes to the runtime,

|
# set this flag to 1. It will cause stage1 to use the snapshot
|
|
# runtime rather than the runtime from the working directory.
