Author	SHA1	Message	Date
Andrew Waterman	c4350ef6ef	Support setting ISA/subsets with --isa flag Default is RV64IMAFDC. Can do things like --isa=RV32 (which implies IMAFDC) --isa=IM (which implies RV64) --isa=RV64IMAFDXhwacha	12 years ago
Andrew Waterman	d9d73d80c1	Simplify RV32 comparisons No need to eliminate the upper 32 bits of the 64-bit x-register, as all RV32 instructions should sign-extend their results to 64 bits.	12 years ago
Andrew Waterman	c8c828b55c	Allow writing mstatus.fs even if FPU isn't present This allows the OS to track FP state dirtiness.	12 years ago
Andrew Waterman	7f3c072750	Implement RVC draft	12 years ago
Andrew Waterman	180554d8f2	Serialize counters without throwing C++ exceptions Ideally, a similar mechanism will apply to target machine exceptions.	12 years ago
Andrew Waterman	41fa048e93	New virtual memory implementation (Sv39)	12 years ago
Andrew Waterman	e5675bfcb3	Update state.pc on every instruction This isn't a bug fix for Spike proper, but it makes it possible for RoCC instructions to access the control thread's PC.	12 years ago
Andrew Waterman	6c965e11dc	For misaligned fetch, set mepc = addr of branch/jump	12 years ago
Yunsup Lee	bc5b666397	bugfix, mbadaddr should be writable	12 years ago
Yunsup Lee	0c1f8bb8b7	change hwacha cause to follow risc-v cause	12 years ago

Yunsup Lee	c0f7d3cd77	bugfix in raising accelerator interrupts	12 years ago
Yunsup Lee	68d1d85208	vxcptsave->vxcptevac,vxcptrestore->vxcpthold this change was necessary since the impl csr is gone.	12 years ago
Andrew Waterman	5378f2942c	Delete all remaining junk on "make clean"	12 years ago
Andrew Waterman	93892690a3	Don't set dirty/referenced bits w/o permission	12 years ago
Andrew Waterman	384e03dde4	Use hcall instead of mcall	12 years ago
Andrew Waterman	11fad84fb1	Implement PTE referenced/dirty bits	12 years ago
Andrew Waterman	ea58df801f	Update to new privileged spec Sorry, everyone.	12 years ago
Yunsup Lee	9af855a28e	correctly parse extension for spike-disasm	12 years ago
Andrew Waterman	c0e63cb0d4	Softfloat fcvt.{w/l}.d now returns -MaxInt for -NaN	12 years ago
Andrew Waterman	7e4df4d518	Softfloat fcvt.{w/h}.s now returns -MaxInt for -NaN Behavior now consistent with RISC-V user spec.	12 years ago
Andrew Waterman	1b15ab2ef5	handle Makefile dependences for precompiled headers correctly	12 years ago
Andrew Waterman	27ade6f544	Install config.h with other headers	12 years ago

Christopher Celio	bf8c76bdbc	Fixed masking/casting logic in commit log printf.	12 years ago
Andrew Waterman	7cbbc8fd6a	Fix commit log I screwed up some stuff in a recent refactoring.	12 years ago

Andrew Waterman	b029a9c67b	Use PATH_MAX instead of NAME_MAX	12 years ago
Stephen Twigg	bd97b5c9fd	Fix bug where C compiler used instead of C++ for autoconf tests	12 years ago
Andrew Waterman	49805d2f17	canonicalize assembler pseudo-ops	12 years ago
Andrew Waterman	17fd25f267	Rename riscv-dis to spike-dasm This is a better name, since it looks for the string DASM(xxx), and it fixes tab completion for the cross compiler.	12 years ago
Andrew Waterman	f971129cb6	Disassemble jalr x0, x1, 0 as ret	12 years ago
Andrew Waterman	c42146fbe4	Require 4-byte instruction alignment until RVC is reimplemented	12 years ago
Andrew Waterman	ec297672b0	On misaligned fetch, set EPC to target, not branch itself	12 years ago
Andrew Waterman	3fd738af16	Reduce dependences on auto-generated code In particular, precompiled headers ideally won't depend on any.	12 years ago
Palmer Dabbelt	e104cd11f5	Merge branch 'netbsd-autoconf' This contains some changes that fix the build on NetBSD.	12 years ago
Palmer Dabbelt	abc20b6543	autoreconf `65ba70071d`	12 years ago
Reinoud Zandijk	65ba70071d	Allow Spike to build on NetBSD Under NetBSD, dlopen() is in libc so no extra libs are needed.	12 years ago
Andrew Waterman	416c8be88c	Support building from within root directory	12 years ago
Andrew Waterman	e26e8c5879	Fix makefile race condition	12 years ago
Andrew Waterman	327a66f990	Merge pull request #11 from arunthomas/readme README: use gnu-toolchain	12 years ago
Arun Thomas	cee386df0d	README: use gnu-toolchain	12 years ago
Andrew Waterman	dd8827e8b3	zero-extend 32b instructions for vxcptaux	12 years ago
Andrew Waterman	d643e43dca	Support 2/4/6/8-byte instructions Most of the complexity is in instruction address translation, since instructions may span page boundaries.	12 years ago
Andrew Waterman	cec752d091	Set badvaddr on instruction page faults This supports distinguishing the EPC (the address of the first byte of the faulting instruction) from the address of the page fault (potentially some bytes later).	12 years ago
Andrew Waterman	992205c270	Update register names to match new ABI	12 years ago
Andrew Waterman	b06c8e9f26	Implement timer faithfully rdcycle/rdinstret now have single-instruction granularity. Questionable behavior when timer interrupts occurred around the same time as the compare register is written should be fixed.	12 years ago
Andrew Waterman	590417bec9	Factor out the dummy RoCC accelerator	12 years ago
Yunsup Lee	c31742961b	Revert "Enable support for the four custom instructions" This reverts commit `fd18dc43f6`. Refactoring support for custom instructions.	12 years ago
