Convex Options
These `-m' options are defined for Convex:
`-mc1'
Generate output for C1. The code will run on any Convex machine.
The preprocessor symbol `__convex__c1__' is defined.
`-mc2'
Generate output for C2. Uses instructions not available on C1.
Scheduling and other optimizations are chosen for max performance
on C2. The preprocessor symbol `__convex_c2__' is defined.
`-mc32'
Generate output for C32xx. Uses instructions not available on C1.
Scheduling and other optimizations are chosen for max performance
on C32. The preprocessor symbol `__convex_c32__' is defined.
`-mc34'
Generate output for C34xx. Uses instructions not available on C1.
Scheduling and other optimizations are chosen for max performance
on C34. The preprocessor symbol `__convex_c34__' is defined.
`-mc38'
Generate output for C38xx. Uses instructions not available on C1.
Scheduling and other optimizations are chosen for max performance
on C38. The preprocessor symbol `__convex_c38__' is defined.
`-margcount'
Generate code which puts an argument count in the word preceding
each argument list. This is compatible with regular CC, and a few
programs may need the argument count word. GDB and other
source-level debuggers do not need it; this info is in the symbol
table.
`-mnoargcount'
Omit the argument count word. This is the default.
`-mvolatile-cache'
Allow volatile references to be cached. This is the default.
`-mvolatile-nocache'
Volatile references bypass the data cache, going all the way to
memory. This is only needed for multi-processor code that does
not use standard synchronization instructions. Making
non-volatile references to volatile locations will not necessarily
work.
`-mlong32'
Type long is 32 bits, the same as type int. This is the default.
`-mlong64'
Type long is 64 bits, the same as type long long. This option is
useless, because no library support exists for it.
