The primary topics in this file are: - - + Global Register Usage - + Stack Frame - + EF bit in the PSR - - -Global Register Usage -===================== - -This information on register usage is based heavily on a comment in the -file gcc-2.7.0/config/sparc/sparc.h in the the gcc 2.7.0 source. - - + g0 is hardwired to 0 - + On non-v9 systems: - - g1 is free to use as temporary. - - g2-g4 are reserved for applications. Gcc normally uses them as - temporaries, but this can be disabled via the -mno-app-regs option. - - g5 through g7 are reserved for the operating system. - + On v9 systems: - - g1 and g5 are free to use as temporaries. - - g2-g4 are reserved for applications (the compiler will not normally use - them, but they can be used as temporaries with -mapp-regs). - - g6-g7 are reserved for the operating system. - - NOTE: As of gcc 2.7.0 register g1 was used in the following scenarios: - - + as a temporary by the 64 bit sethi pattern - + when restoring call-preserved registers in large stack frames - -RTEMS places no constraints on the usage of the global registers. Although -gcc assumes that either g5-g7 (non-V9) or g6-g7 (V9) are reserved for the -operating system, RTEMS does not assume any special use for them. - - - -Stack Frame -=========== - -The stack grows downward (i.e. to lower addresses) on the SPARC architecture. - -The following is the organization of the stack frame: - - - - | ............... | - fp | | - +-------------------------------+ - | | - | Local registers, temporaries, | - | and saved floats | x bytes - | | - sp + x +-------------------------------+ - | | - | outgoing parameters past | - | the sixth one | x bytes - | | - sp + 92 +-------------------------------+ * - | | * - | area for callee to save | * - | register arguments | * 24 bytes - | | * - sp + 68 +-------------------------------+ * - | | * - | structure return pointer | * 4 bytes - | | * - sp + 64 +-------------------------------+ * - | | * - | local register set | * 32 bytes - | | * - sp + 32 +-------------------------------+ * - | | * - | input register set | * 32 bytes - | | * - sp +-------------------------------+ * - - -* = minimal stack frame - -x = optional components - -EF bit in the PSR -================= - -The EF (enable floating point unit) in the PSR is utilized in this port to -prevent non-floating point tasks from performing floating point -operations. This bit is maintained as part of the integer context. -However, the floating point context is switched BEFORE the integer -context. Thus the EF bit in place at the time of the FP switch may -indicate that FP operations are disabled. This occurs on certain task -switches, when the EF bit will be 0 for the outgoing task and thus a fault -will be generated on the first FP operation of the FP context save. - -The remedy for this is to enable FP access as the first step in both the -save and restore of the FP context area. This bit will be subsequently -reloaded by the integer context switch. - -Two of the scenarios which demonstrate this problem are outlined below: - -1. When the first FP task is switched to. The system tasks are not FP and -thus would be unable to restore the FP context of the incoming task. - -2. On a deferred FP context switch. In this case, the system might switch -from FP Task A to non-FP Task B and then to FP Task C. In this scenario, -the floating point state must technically be saved by a non-FP task. diff --git a/cpukit/score/cpu/sparc/asm.h b/cpukit/score/cpu/sparc/asm.h deleted file mode 100644 index a3d62416b8..0000000000 --- a/cpukit/score/cpu/sparc/asm.h +++ /dev/null @@ -1,111 +0,0 @@ -/* asm.h - * - * This include file attempts to address the problems - * caused by incompatible flavors of assemblers and - * toolsets.
