This is an optimization hack which should only be present

in a sparc 32bit driver of the compiler compiled with

|
|
6693b3 |
host/target/build sparc64-redhat-linux --with-cpu=v7.
|
|
|
6693b3 |
As long long HOST_WIDE_INT slows things down, we can have in
|
|
|
6693b3 |
addition to the sparc64-*/3.2/{cc1,cc1plus}
|
|
|
6693b3 |
sparc-*/3.2/{cc1,cc1plus} binaries which are suitable for compiling
|
|
|
6693b3 |
-m32 code only, but use long HOST_WIDE_INT.
