Author	SHA1	Message	Date
Andrew Waterman	47a2e87ccd	Support CFI shadow stacks via --zicfiss command-line arg	2 years ago
Ming-Yi Lai	a227544788	Zicfilp: Handle software check exception -- landing pad fault	2 years ago
Andrew Waterman	4f1e335585	pk: make breakpoints fatal Resolves #216	5 years ago
Andrew Waterman	fe4118a691	pk: remove vestigial trapframe_t::insn field This assumes that stval is populated with the opcode on illegal instruction exceptions. But since we're only using the opcode for error reporting, it's OK if this assumption is violated.	5 years ago
Andrew Waterman	b9eba474fb	pk: support >2 GiB of user memory for RV64 Previously, the pk would always run from virtual address MEM_START. Instead, remap it into the negative virtual addresses, allowing user processes to expand beyond MEM_START.	5 years ago
wxjstz	41ff94a84c	Add some exception handling functions to s-mode to handle exception return from m-mode. (#117)	8 years ago

Andrew Waterman	069bdd3f0d	Implement draft of new calling convention Here is the new syscall ABI: syscall number in a7 args in a0 - a6 return value in a0 Here is the integer register map: x0 -> x0 x1 -> ra x2 -> sp x3 -> tp x4 -> gp x5 -> t0 x6 -> t1 x7 -> t2 x8 -> s0 x9 -> s1 x10 -> a0 x11 -> a1 x12 -> a2 x13 -> a3 x14 -> a4 x15 -> a5 x16 -> a6 x17 -> a7 x18 -> s2 x19 -> s3 x20 -> s4 x21 -> s5 x22 -> s6 x23 -> s7 x24 -> s8 x25 -> s9 x26 -> s10 x27 -> s11 x28 -> t3 x29 -> t4 x30 -> t5 x31 -> t6	12 years ago
