Andrew Waterman	74ee3b7616	Refine Zicfiss overlap list We get better error checking if we list only the more specific instructions and omit the more general ones (mop.r.N/mop.rr.N).	2 years ago
Andrew Waterman	5defb11363	Remove unnecessary instructions from overlap list - c.fsdsp need not be listed since cm.push etc. are listed - mop.r.28/mop.rr.7 don't have corresponding files in riscv/insns/ - the rest are just erroneous	2 years ago

YenHaoChen	db762327ef	triggers: implement tcontrol Implement Debug spec Section 5.7.6. Trigger Control (tcontrol). This commit lets tcontrol be read-only 0 if number of triggers is 0.	2 years ago

Andrew Waterman	759599553b	Avoid checking ELP before every instruction fetch Serialize after setting ELP. That way, we can hoist the check outside of the main simulation loop.	2 years ago
Andrew Waterman	148e6d63e0	No need to check if Zicfilp is enabled before checking ELP ELP will be zero if Zicfilp is not enabled.	2 years ago

Jerry Zhao	3a70f84b8a	Merge pull request #1670 from clementleger/dev/cleger/et_dyn add support to load ET_DYN elf	2 years ago
Clément Léger	a316a37331	add support to load ET_DYN elf When compiled as PIE, executable can be loaded at any memory address. Lately, OpenSBI switched to such behavior and spike was not able to load it anymore. This patch add an additional load_offset parameter for load_elf(). This load_offset value is passed as DRAM_BASE and used only for ET_DYN elfs. Signed-off-by: Clément Léger <cleger@rivosinc.com>	2 years ago

Andrew Waterman	4611b1f7f9	Merge pull request #1675 from chihminchao/cfi-fix zicflip: fix [ms]ret behavior	2 years ago
YenHaoChen	8ad1b68911	vector: Not logging write of reduction instructions when vl = 0 The spec says: "If vl=0, no operation is performed and the destination register is not updated." in Section 14. Vector Reduction Operations. The commit proposes setting the variable is_write to false when vl = 0, which means not logging the write.	2 years ago
Chih-Min Chao	853105c659	zicflip: fix [ms]ret behavior Based on Spec chapter 3.5 "An MRET or SRET instruction is used to return from a trap in M-mode or S-mode, respectively. When executing an xRET instruction, if xPP holds the value y, then ELP is set to the value of xPELP if yLPE is 1; otherwise, it is set to NO_LP_EXPECTED; xPELP is set to NO_LP_EXPECTED." The change follow the last statement after semicolon "xPELP is set to NO_LP_EXPECTED" Signed-off-by: Chih-Min Chao <chihmin.chao@sifive.com>	2 years ago

LIU Yu	e7e039dece	Support per-device arguments and device factory reuse As proposed in #1652, we made the following changes to MMIO device (factory) plugin API, to mitigate current limitations and facilitate factory reuse. - removed `sargs` from `device_factory_t`, and introduced a new type alias `device_factory_sargs_t` to capture `<device_factory_t *, sargs>` pairs, this is used to instantiate sim_t instances; - changed the signature of `device_factory_t::generate_fdt` and `device_factory_t::parse_from_fdt` to take on an extra `sargs` argument, for instantiating devices with per-device arguments; - made `device_factory_t` const and potentially resuable across multiple `sim_t` instances.	2 years ago
