2016-01-23mips: Clean up includesPeter Maydell1-0/+1
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes.

2016-01-22fpu: Replace int32 typedef with int32_tPeter Maydell1-12/+12
Replace the int32 softfloat-specific typedef with int32_t. This change was made with find hw include fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\bint32\b/int32_t/g' together with manual removal of the typedef definition, and manual undoing of some mis-hits where macro arguments were being used for token pasting rather than as a type. The uses in hw/ipmi/ should not have been using this type at all.

2015-09-18target-mips: improve exception handlingPavel Dovgaluk1-73/+85
This patch improves exception handling in MIPS. Instructions generate several types of exceptions. When exception is generated, it breaks the execution of the current translation block. Implementation of the exceptions handling does not correctly restore icount for the instruction which caused the exception. In most cases icount will be decreased by the value equal to the size of TB. This patch passes pointer to the translation block internals to the exception handler. It allows correct restoring of the icount value.

2015-07-15target-mips: fix to clear MSACSR.CauseYongbok Kim1-0/+6
MSACSR.Cause bits are needed to be cleared before a vector floating-point instructions. FEXDO.df, FEXUPL.df and FEXUPR.df were missed out.

2015-03-11target-mips: add missing MSACSR and restore fp_status and hflagsLeon Alrae1-11/+1
Save MSACSR state. Also remove fp_status, msa_fp_status, hflags and restore them in post_load() from the architectural registers. Float exception flags are not present in vmstate. Information they carry is used only by softfloat caller who translates them into MIPS FCSR.Cause, FCSR.Flags and then they are cleared. Therefore there is no need for saving them in vmstate.

Reduce line wrapping throughout MSA helper macros by using a local float status pointer rather than referring to the float status through the environment each time. No functional change.
