Dear gcc developers,
I would like to ask, whether there are plans to support default 64-bit
integers in g77 and gcc on ia64. I mean something equivalent to the
-i8 option of the intel efc compiler, which sets fortran integer variables
to 8-byte default and in C sets sizeof(int)=8. As far as I understand, this
would require also appropriatelly compiled libraries.
As far as the g77 side goes, I researched this in 1996 and it turned out
to be too hard (due to assumptions made in the g77 front-end).
g95 will support -i8 (and -r8) but it is still some years away (see URL
below).
Sorry,
