This is an optimization hack which should only be present
|
|
|
4ac4fd |
in a sparc 32bit driver of the compiler compiled with
|
|
|
4ac4fd |
host/target/build sparc64-redhat-linux --with-cpu=v7.
|
|
|
4ac4fd |
As long long HOST_WIDE_INT slows things down, we can have in
|
|
|
4ac4fd |
addition to the sparc64-*/3.2/{cc1,cc1plus}
|
|
|
4ac4fd |
sparc-*/3.2/{cc1,cc1plus} binaries which are suitable for compiling
|
|
|
4ac4fd |
-m32 code only, but use long HOST_WIDE_INT.
