* Add a quick test helper macro to test_x86.c
* Add regression tests for bswap and rex prefixes
* Properly ignore REX prefixes when appropriate
* Fix bswap ax emulator detection
uc->target_page_align is a uint32_t. When the binary not will only
invert the 32 bit of the value. Used this in a binary and operator with
a uint64_t will case the upper 32bit of the address to be 0. Therefor
the bug only appears when the upper 32bit of the address are used.
Now a local uint64_t variable is used for the alignemend and the test
uses a not page alligned address which does not fit in 32bit.
Access to TB, DEC registers was lead to crash
spr_read_decr and others are changed to spr_read_generic
spr_write_decr and others are changed to spr_write_generic
Uses Copy on Write to make it posible to restore the memory state after a snapshot
was made. To restore all MemoryRegions created after the snapshot are removed.
RISCV FP registers are 64-bit in size, even in 32-bit mode, because they can
hold doubles. The test even uses the double-precision instruction fmv.d. Thus,
the reads should be reading 64-bit registers.
uc_ctl_flush_tlb implies that the tlb is flushed. This change adds
UC_CTL_TLB_FLUSH which clears the TLB and set the uc_ctl_flush_tlb
alias to UC_CTL_TLB_FLUSH. Also adds a uc_ctl_flush_tb alias for
UC_CTL_TB_FLUSH.
Unicorn has included some ugly hacks to provide a envirement where vaddr == paddr.
These hacks where to use the full 64 bit mappings on x86 without init the mmu
and some memory redirect for MIPS.
The UC_TLB_CPU mode defaults to vaddr == paddr, therfor these hacks aren't
required anymore.
Some simple tests for diffrent mmu.
Basicly add some tlb entries, enable the mmu try to read from virtual address
The aarm64 test was provided by imre-kis-arm in #1718
quit_request is for internal use. This means the IP register was updated and
qemu needs to rebuild the translation blocks.
stop_request is set by the user (uc_emu_stop) to indecate that unicorn sould
stop emulating.
On machines with a page size larger than 4K, the requested memory size
in `test_map_big_memory` gets rounded up and overflows to zero.
This PR adds some code to query the page size and adjust the requested
memory size accordingly.
