      target-sparc: Add and use CPU_FEATURE_CASA · 16c358e9
      Sebastian Huber 提交于
      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.

      Rename target_phys_addr_t to hwaddr · a8170e5e
      Avi Kivity 提交于
      target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
      reserved) and its purpose doesn't match the name (most target_phys_addr_t
      addresses are not target specific).  Replace it with a finger-friendly,
      standards conformant hwaddr.
      
      Outstanding patchsets can be fixed up with the command
      
        git rebase -i --exec 'find -name "*.[ch]"
                              | xargs s/target_phys_addr_t/hwaddr/g' origin
