2019-12-04sparc: Fix the predecoder's moreBytes method.Gabe Black
Endianness transformation was moved from the CPU into this method, making the "inst" parameter guest endian instead of host endian. The emi member of the decoder was set using the betoh method, ensuring that it was still stored in host order. Unfortunately, the "inst" parameter was used in some places when setting up the rest of emi. This change replaces those uses of inst with emi.

2019-12-03cpu,sim-se: move error checks in syscall methodsBrandon Potter
There is a check on a global flag denoting that the simulator has been configured to run in fullsystem mode. The check is conducted at runtime during calls to syscall methods. The high-level models are checking the flag when the check could be conducted further down the call chain (nearer to the actual Process invocation). Moving the checks should result in less copy-pasta as new models are developed. It might be argued that the checks should stay in place since an error would detected earlier; that may be true, but the error would be the same and the simulation should fail in either case. This arrangement requires fewer lines of code. The changeset also changes the check into a fatal error instead of a panic since usage (in fs mode) should result in immediate corruption.

2019-11-27base, python: Allow dirname selection for the interpreterGiacomo Travaglini
This is the second step towards being able to run dynamically linked applications when the guest ISA != than host ISA. Once the guest interpreter is loaded to memory, we are able to redirect shared object loads through the redirectPath interface. How do we load the guest interpreter? The elf file is for example asking for the /lib/ld-linux-aarch64.so interpreter. That would point to a valid dynamic linker/loader if guest ISA == host ISA, but if we are running on X86 we should point to the guest (aarch64 in the example) toolchain wherever it is installed. This patch is adding the --interp-dir option to point to the parent folder of the guest /lib in the host fs.

2019-11-25arch-riscv: Fix disassembling of operand list for compressed instructionsIan Jiang
In disassembling compressed instructions, the original Gem5 gives needless operands, such as register or immediate. This patch fixes the problem. - Existing formats fixed: CIOp, CJOp, CBOp and Jump. - New formats added: CIAddi4spnOp (for c.addi4spn only) and CompressedROp (with templates CBasicDeclare and CBasicExecute) Change-Id: Ic293836983256a59d3a7aca091c8184b410516a4 Signed-off-by: Ian Jiang <ianjiang.ict@gmail.com> Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/22566 Tested-by: kokoro <noreply+kokoro@google.com> Reviewed-by: Jason Lowe-Power <jason@lowepower.com> Reviewed-by: Alec Roelke <alec.roelke@gmail.com> Maintainer: Alec Roelke <alec.roelke@gmail.com>
2019-11-25arch-riscv: Fix disassembling of immediate for U-type instructionsIan Jiang
For U-type instructions auipc and lui, the 20-bit immediate is left-shifted by 12 bits in decoding. While the original Gem5 gives the left-shifted value directly in disassembly. This patch fixes the problem by - Assign the original 20-bit immediate to internal variable "imm". - Output "imm" directly in disassembly, as how the original Gem5 does. - Do the left-shift to "imm" later in the function defining of each instruction, rather than in decoding.

When serialize and unserialize an variable, the parameters passed to SERIALIZE_SCALAR() and UNSERIALIZE_SCALAR() must be the same and should be a general variable name.

These tests assume the "end address" is not included in the range. This exposed some bugs in addr_range.hh which have been fixed. Where appropriate code comments in addr_range.hh have been extended to improve understanding of the class's behavior. Hard-coded AddrRange values in the project have been updated to take into account that end address is now exclusive. The python params.py interface has been updated to conform to this new standard.

2019-11-18arch: Get rid of the (Big|Little)EndianGuest namespaces.Gabe Black
These namespaces were used to set up an environment/context where there was an implicit guest namespace. This is an issue when there may be multiple guest endiannesses which might be different. In cases where we don't know what the guest endianness is, we can't rely on it being an implicit part of our context since that would be ambiguous. In cases where we do know, for instance in ISA specific code, we can just use the endianness specific version that's appropriate for that context. This also (somewhat) removes the assumption that there is a single endianness that applies for a particular ISA. Practically speaking this assumption will probably still stand though, since there would likely be a non-trivial performance penalty to apply a configurable endianness instead of a fixed one the compiler can optomize/remove.
