Change-Id: I81047a4ac68e11a37882175732e4985c2f43a183
2022-07-29ripple/minitrace: match identifier style in macrosedef
Having macro identifiers match the "real" identifier style makes macro code markedly more readable. Change-Id: Ib675390cc04941ce782c75b2ee686709441081fc
2022-07-29ripple/minitrace: pluralise newfstatat flags parameteredef

Change-Id: Iaf6d5717e2d83a6f81fda34da086311d21f345c2
2022-07-28ripple/minitrace: mark file descriptor parametersedef
This doesn't specifically handle * the distinction between borrowed/owned file descriptors (in non-return positions, that only applies to `close`) * "nullable" fd parameters (-1 for not-present) * other sentinel fds, like AT_FDCWD * fd validity in general Change-Id: I00fa68ec94b8f24e28c661d0c007becb37c0a5f3
2022-07-27ripple/minitrace: remove GRND_ prefix from GrndFlagsedef

2022-07-27ripple/minitrace: mmap fd is an i32, not u64edef

2022-07-27ripple/minitrace: better errors for invalid syscall argsedef
Change-Id: I26356c9b88c838e3c87e4083ac17f958c7c57bb7
2022-07-27ripple/minitrace: introduce syscall_bitflags!edef
Squeeze the bitflags / SyscallArg impl boilerplate into one macro. Change-Id: I5b5213b6f3ee11bc61b6f8439ceb2510ef6dffec
2022-07-27ripple/minitrace: implement SyscallArg for bitflagsedef

2022-07-27ripple/minitrace: disable dead_code lint on SyscallArgsedef
Every single syscall arg producing a warning is just noisy. Change-Id: I339260886110e2982217ebbf9d29cb1cf91c747c
2022-07-27ripple/minitrace: refactor syscall interpretationV
We separate type-based parsing of syscall arguments from more detailed validation based on multiple parameters or on specific values. The former is implemented with a macro that takes syscall signatures and generates the relevant enum variant and parsing code. Co-authored-by: edef <edef@unfathomable.blue> Change-Id: I7e334d3e128e7b1461bfd6fae7c8ec5dd6ada0a8
2022-07-27ripple/minitrace: fix newfstatat dirfd handlingedef
Same bug as Ied63822001c8700fc71c89ec16d18036fbc33972, hiding missing behaviour around dirfd. newfstatat(AT_FDCWD, path, …) is used, as is newfstatat(fd, "", …). Change-Id: I03b9dc5118d7a47514abef82c4a577e8362fbb4d
2022-07-08ripple/minitrace: convert openat dirfd correctlyedef
Our conversion always mangled it, *and* our comparison was inverted, so both bugs remained hidden. Change-Id: Ied63822001c8700fc71c89ec16d18036fbc33972
2022-06-19ripple/minitrace: fix syscall ABIV
The fourth argument is passed in r10, not rcx, which is merely clobbered by syscalls. Change-Id: I0c7210c621f6955deccf21348ce6f495424555cc
2022-06-17ripple/minitrace: add set_tid_address, set_robust_list, and getrandomV

2021-12-27ripple/minitrace: enforce permitted syscall numbersedef
This doesn't discriminate between muxed syscalls yet, but at least bounds the available syscalls to the ones `cc1 hello.c` invokes. Change-Id: I1965f27746b509b32d5e86510e803038765c11dd
