2014-03-13cpu: Move breakpoints field from CPU_COMMON to CPUStateAndreas Färber1-2/+2
Most targets were using offsetof(CPUFooState, breakpoints) to determine how much of CPUFooState to clear on reset. Use the next field after CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise. Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-03-12target-sparc: Add and use CPU_FEATURE_CASASebastian Huber1-17/+32
The LEON3 processor has support for the CASA instruction which is normally only available for SPARC V9 processors. Binutils 2.24 and GCC 4.9 will support this instruction for LEON3. GCC uses it to generate C11 atomic operations. The CAS synthetic instruction uses an ASI of 0x80. If TARGET_SPARC64 is not defined use a supervisor data load/store for an ASI of 0x80 in helper_ld_asi()/helper_st_asi(). The supervisor data load/store was choosen according to the LEON3 documentation. The ASI 0x80 is defined in the SPARC V9 manual, Table 12—Address Space Identifiers (ASIs). Here we have: 0x80, ASI_PRIMARY, Unrestricted access, Primary address space. Tested with the following program: #include <assert.h> #include <stdatomic.h> void test(void) { atomic_int a; int e; _Bool b; atomic_store(&a, 1); e = 1; b = atomic_compare_exchange_strong(&a, &e, 2); assert(b); assert(atomic_load(&a) == 2); atomic_store(&a, 3); e = 4; b = atomic_compare_exchange_strong(&a, &e, 5); assert(!b); assert(atomic_load(&a) == 3); } Tested also on a NGMP board with a LEON4 processor.
