I was just looking at the documentation for g77 and noticed the following, and also noticed that it is not used when fortran for a package is compiled with the default (i.e. no Makefile in src directory.) Should it be considered? Paul Gilbert _____ `-malign-double' (Intel x86 architecture only.) Noticeably improves performance of `g77' programs making heavy use of `REAL(KIND=2)' (`DOUBLE PRECISION') data on some systems. In particular, systems using Pentium, Pentium Pro, 586, and 686 implementations of the i386 architecture execute programs faster when `REAL(KIND=2)' (`DOUBLE PRECISION') data are aligned on 64-bit boundaries in memory. This option can, at least, make benchmark results more consistent across various system configurations, versions of the program, and data sets. *Note:* The warning in the `gcc' documentation about this option does not apply, generally speaking, to Fortran code compiled by `g77'. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
