| 26 # This script is used only from top.make. | |
| 27 # The macro $(MFLAGS-adjusted) calls this script to | |
| 28 # adjust the "-j" arguments to take into account | |
| 29 # the HOTSPOT_BUILD_JOBS variable. The default | |
| 30 # handling of the "-j" argument by gnumake does | |
| 31 # not meet our needs, so we must adjust it ourselves. | |
| 32 | |
| 33 # This argument adjustment applies to two recursive | |
| 34 # calls to "$(MAKE) $(MFLAGS-adjusted)" in top.make. | |
| 35 # One invokes adlc.make, and the other invokes vm.make. | |
| 36 # The adjustment propagates the desired concurrency | |
| 37 # level down to the sub-make (of the adlc or vm). | |
| 38 # The default behavior of gnumake is to run all | |
| 39 # sub-makes without concurrency ("-j1"). | |
| 40 | |
| 41 # Also, we use a make variable rather than an explicit | |
| 42 # "-j<N>" argument to control this setting, so that | |
| 43 # the concurrency setting (which must be tuned separately | |
| 44 # for each MP system) can be set via an environment variable. | |
| 45 # The recommended setting is 1.5x to 2x the number of available | |
| 46 # CPUs on the MP system, which is large enough to keep the CPUs | |
| 47 # busy (even though some jobs may be I/O bound) but not too large, | |
| 48 # we may presume, to overflow the system's swap space. | |
