2014-05-28tcg: Invert the inclusion of helper.hRichard Henderson
Rather than include helper.h with N values of GEN_HELPER, include a secondary file that sets up the macros to include helper.h. This minimizes the files that must be rebuilt when changing the macros for file N. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>

2014-03-13cpu: Turn cpu_handle_mmu_fault() into a CPUClass hookAndreas Färber
Note that while such functions may exist both for *-user and softmmu, only *-user uses the CPUState hook, while softmmu reuses the prototype for calling it directly. Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-03-13target-sparc: Clean up ENV_GET_CPU() usageAndreas Färber
Commits fdfba1a298ae26dd44bcfdb0429314139a0bc55a, 2c17449b3022ca9623c4a7e2a504a4150ac4ad30 and f606604f1c10b60ef294f1b9b229426521a365e3 added usages of ENV_GET_CPU() macro in target-specific code. Use sparc_env_get_cpu() instead and reuse the variables. Cc: Edgar E.

2014-03-12target-sparc: Add and use CPU_FEATURE_CASASebastian Huber
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.

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity
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 Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
