* target/riscv: setup everything for rv64 to support rv128 executionFrédéric Pétrot2022-01-081-0/+5
| | | | | | | | | | | | | | | | | This patch adds the support of the '-cpu rv128' option to qemu-system-riscv64 so that we can indicate that we want to run rv128 executables. Still, there is no support for 128-bit insns at that stage so qemu fails miserably (as expected) if launched with this option.

* osdep: protect qemu/osdep.h with extern "C"Paolo Bonzini2021-04-172-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | System headers may include templates if compiled with a C++ compiler, which cause the compiler to complain if qemu/osdep.h is included within a C++ source file's 'extern "C"' block. Add an 'extern "C"' block directly to qemu/osdep.h, so that system headers can be kept out of it. There is a stray declaration early in qemu/osdep.h, which needs to be special cased. Add a definition in qemu/compiler.h to make it look nice. config-host.h, CONFIG_TARGET, exec/poison.h and qemu/compiler.h are included outside the 'extern "C"' block; that is not an issue because they consist entirely of preprocessor directives. This allows us to move the include of osdep.h in our two C++ source files outside the extern "C" block they were previously using for it, which in turn means that they compile successfully against newer versions of glib which insist that glib.h is *not* inside an extern "C" block.

This is caused by passing the wrong value to the read_memory_func(). The intention is that at this point in the loop the 'cap_buf' buffer already contains 'csize' bytes of data for the instruction at guest addr 'pc', and we want to read in an extra 'tsize' bytes. Those extra bytes are therefore at 'pc + csize', not 'pc'. On the first time through the loop 'csize' happens to be zero, so the initial read of 32 bytes into cap_buf is correct and as long as the disassembly never needs to read more data we return the correct information. Use the correct guest address in the call to read_memory_func().

This patch adds support for 'mffsl'. 'mffsl' is identical to 'mffs', except it only returns mode, status, and enable bits from the FPSCR. On CPUs without support for 'mffsl' (below ISA 3.0), the 'mffsl' instruction will execute identically to 'mffs'. Note: I renamed FPSCR_RN to FPSCR_RN0 so I could create an FPSCR_RN mask which is both bits of the FPSCR rounding mode, as defined in the ISA. I also fixed a typo in the definition of FPSCR_FR.

* disas: Rename include/disas/bfd.h back to include/disas/dis-asm.hMarkus Armbruster2019-04-1820-20/+20
| | | | | | | | | | | | | | | | Commit dc99065b5f9 (v0.1.0) added dis-asm.h from binutils. Commit 43d4145a986 (v0.1.5) inlined bfd.h into dis-asm.h to remove the dependency on binutils. Commit 76cad71136b (v1.4.0) moved dis-asm.h to include/disas/bfd.h. The new name is confusing when you try to match against (pre GPLv3+) binutils. Rename it back. Keep it in the same directory, of course.
