Various changes to support OSF1 emulation:

* Move the user stack from VM_MAXUSER_ADDRESS to a place below the 32bit boundary (needed to support 32bit OSF programs). This should also save one pagetable per process. * Add cvtqlsv to the set of instructions handled by the floating point software completion code. * Disable all floating point exceptions by default. * A minor change to execve to allow the OSF1 image activator to support dynamic loading.

Implement fpsetmask() and other fp*() functions. Programs should use

Little reorganization:

- created internal names for fixed-size integral types, like __int32_t. They will be used to make several headers self-sufficient. - don't include anymore. - created , which can be used as . - declaration of uoff_t and ufs_daddr_t moved to . Reviewed by: bde

Implement 'software completion' for floating point arithmetic. On the

alpha, operations involving non-finite numbers or denormalised numbers or operations which should generate such numbers will cause an arithmetic exception. For programs which follow some strict code generation rules, the kernel trap handler can then 'complete' the operation by emulating the faulting instruction. To use software completion, a program must be compiled with the arguments '-mtrap-precision=i' and '-mfp-trap-mode=su' or '-mfp-trap-mode=sui'. Programs compiled in this way can use non-finite and denormalised numbers at the expense of slightly less efficient code generation of floating point instructions. Programs not compiled with these options will receive a SIGFPE signal when non-finite or denormalised numbers are used or generated. Reviewed by: John Polstra
