2018-11-02util: Move the existing systemc example into a subdirectory.Gabe Black
This example is for how to embed gem5 within systemc and make it use the systemc event queue. This used to be the only method of using gem5 and systemc together, but now that there are other options, it's ambiguous to have it as the only thing in the util/systemc directory. This change moves it into a gem5_within_systemc subdirectory which clearly shows what type of integration that example corresponds with.

Unfortunately, this breaks when using `make -C <path>`, as -C does not move PWD accordingly. The fix is simply to remove $(PWD), as a relative path is just fine here.

2018-06-15tests,style: add RISC-V assembly testsTuan Ta
This patch adds a subset (rv64*) of RISC-V assembly tests. The original riscv-test project can be found here: https://github.com/riscv/riscv-tests. The riscv-test project is under the BSD license (https://github.com/riscv/riscv-tests/blob/master/LICENSE) and is maintained separately from gem5 project. The tests have been slightly modified to work in gem5 SE mode: (1) Removed a trap handler used in riscv-tests for bare-metal systems (2) Instead of throwing an exception, the tests call the exit syscall with the exit code of - '0' if SUCCESS - Failed test case's number (non-zero) if FAILURE The exit code can be captured after a simuation completes. In addition to original RISC-V assembly tests, this patch adds several assembly tests specifically for AMO, LR, SC and system calls. Those tests target a multi-core system. (1) rv64uamt: multi-threaded tests for A-extension instructions (2) rv64samt: multi-threaded tests for clone and futex system calls This patch also makes the style checker ignore RISC-V assembly test directory. The assembly tests are maintained in an external project that does not follow the gem5 coding conventions. Please find more details in the README file included in this patch.

This helps performance, but sometimes misclassifies changes that exist both in the upstream branch before the branch point and in a feature branch. Such changes should normally not exist, but can be the product of an incorrect rebase. This change adds an option to the helper script to search the entire upstream repo history when determining the set of upstream changes. When this option is provided, the script lists the changes that exist upstream before the branch point and in the feature branch as "Incorrectly rebased changes".

2017-05-09util, arm: Support mmapped m5ops on aarch64Andreas Sandberg
Add support for memory-mapped m5ops in the aarch64 version of the m5 utility.

2017-05-09util: Correctly handle short writes in m5 (read|exec)fileAndreas Sandberg
The m5 tool has subcommands that writes a file to the simulated file system. The implementation of this command currently doesn't check the return value from write, which leads to compiler warnings and potentially incorrect behavior. Add the necessary checks.

2017-05-09util: Fix incorrect use of m5_loadsymbolAndreas Sandberg
It seems like the m5 utility incorrectly called m5_loadsymbol instead of m5_addsymbol. Judging by the signature of the loadsymbol command, the expected behavior is to add a new symbol to gem5's symbol table. This is behavior is implemented by m5_addsymbol.
