2011-11-19Improve "ta 0" shutdownFabien Chouteau
This patch replace the previous implementation with this simplified and more complete version (no shutdown when psret == 1). Signed-off-by: Fabien Chouteau <chouteau@adacore.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-10-26target-sparc: Implement ALIGNADDR* inline.Richard Henderson
While ALIGNADDR was implemented out-of-line, ALIGNADDRL was not implemeneted at all. However, this is a very simple operation so we're better off doing this inline. Signed-off-by: Richard Henderson <rth@twiddle.net>

2011-10-26target-sparc: Do exceptions management fully inside the helpers.Richard Henderson
This reduces the size of the individual translation blocks, since we only emit a single call for each FOP rather than three. In addition, clear_float_exceptions expands inline to a single byte store. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-10-26target-sparc: Change fpr representation to doubles.Richard Henderson
This allows a more efficient representation for 64-bit hosts. It should be about the same for 32-bit hosts, as we can still access the individual pieces of the double. Signed-off-by: Richard Henderson <rth@twiddle.net>

2011-10-26target-sparc: Add accessors for double-precision fpr access.Richard Henderson
Begin using i64 quantities to manipulate double-precision values. On a 64-bit host this will, for the moment, generate less efficient code; on a 32-bit host code quality should be largely unchanged. Code quality for 64-bit will be adjusted with a subsequent patch. Signed-off-by: Richard Henderson <rth@twiddle.net>

Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-10-26target-sparc: Add accessors for single-precision fpr access.Richard Henderson
Load, store, and "create destination". This version attempts to change the behaviour of the translator as little as possible. We previously used cpu_tmp32 as the temporary destination, and we continue to use that. This will eventually allow a change in representation of the fprs. Change the name of the cpu_fpr array to make certain that all instances are converted. Signed-off-by: Richard Henderson <rth@twiddle.net>

2011-10-25target-sparc: Fix use of g_new0 / g_freeStefan Weil

2011-10-25target-sparc: Fix order of function parametersStefan Weil
The MinGW-w64 gcc complains about wrong parameters for gen_helper_fpadd16_s and three other functions. gen_helper_fpadd16_s is declared like this (hidden in lots of macros): static inline void gen_helper_fpadd16s(TCGv_i32 retval, TCGv_ptr arg1, TCGv_i32 arg2, TCGv_i32 arg3); So it looks like cpu_env should be the 2nd parameter. Please review this patch as I have no environment to test it (maybe the 1st parameter should be cpu_dst?).

2011-09-10Gdbstub: Fix back-trace on SPARC32Fabien Chouteau
Gdb expects all registers windows to be flushed in ram, which is not the case in Qemu. Therefore the back-trace generation doesn't work.

2011-08-01Sparc: fix non-faulting unassigned memory accessesBlue Swirl
Commit b14ef7c9ab41ea824c3ccadb070ad95567cca84e introduced cpu_unassigned_access() function. On Sparc, the function does not restore AREG0 used for global CPUState on function exit, causing bugs with non-faulting unassigned memory accesses. Alpha, Microblaze and MIPS are not affected. Fix by restoring AREG0 on exit. Remove excess saving by do_unassigned_access() functions. Also ignore unassigned accesses outside of CPU context.

2011-07-30exec.h cleanupBlue Swirl
Move softmmu_exec.h include directives from target-*/exec.h to target-*/op_helper.c. Move also various other stuff only used in op_helper.c there. Define global env in dyngen-exec.h. For i386, move wrappers for segment and FPU helpers from user-exec.c to op_helper.c. Implement raise_exception_err_env() to handle dynamic CPUState. Move the function declarations to cpu.h since they can be used outside of op_helper.c context. LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and env_to_regs(). ARM: make raise_exception() static. Convert #include "exec.h" to #include "cpu.h" #include "dyngen-exec.h" and remove now unused target-*/exec.h. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-07-21SPARC64: implement addtional MMU faults related to nonfaulting loadTsuneo Saito
This patch implements MMU faults caused by TTE.NFO and TTE.E: - access other than nonfaulting load to a page marked NFO should raise data_access_exception - nonfaulting load to a page marked with E bit should raise data_access_exception To distinguish nonfaulting loads, this patch extends (abuses?) the rw argument of get_physical_address_data(). rw is set to 4 on nonfaulting loads.
