Convex
Options
The following ‘-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.
