jas.git, branch mainA RISC-V assembler using Bison & Flexhttps://git.mcdonnell.dev/jas.git/atom?h=main2026-04-21T23:56:41Zfeat: Encoded Assembly Instructions2026-04-21T23:56:41ZJacob McDonnelljacob@jacobmcdonnell.com2026-04-21T23:56:41Zurn:sha1:ef375d2a484fd0c3dced72174f0dc39694de433a
Initial Encoding of assembly instructions in C++ structs.
feat: Initial mapping of registers and instructions2026-03-16T01:51:55ZJacob McDonnelljacob@jacobmcdonnell.com2026-03-16T01:51:55Zurn:sha1:2999bd3b9466617938f2f7ceb689cfbe33b46cd9
Mapping of registers from register names to numbers. As well, the inital
mapping of instructions to their opcodes has been added. There are bit
fields for each type of instruction, and a tagged union of all the
instruction types.
refactor: Explicit register names & instructions2026-03-16T00:59:54ZJacob McDonnelljacob@jacobmcdonnell.com2026-03-16T00:59:54Zurn:sha1:7025f30be3b6cccf9f419daec9f0b7aeeaa2d6d3
Explicit tokenization of register names and instructions. This forces
stricter syntax conformance and prevents errors from slipping through.
This also prevents the user from using these keywords as names other
than for their intended use.
feat: Parsing modifiers and directives2026-03-16T00:03:26ZJacob McDonnelljacob@jacobmcdonnell.com2026-03-16T00:03:26Zurn:sha1:efb0a239c4aaee370d97caf216859a724d7f72bd
Support added for parsing a limited set of directives and for all access
modifiers.
refactor!: Switched from x86_64 to RISC-V2026-03-15T00:45:12ZJacob McDonnelljacob@jacobmcdonnell.com2026-03-15T00:45:12Zurn:sha1:68b9f87bc3b6bd6ccb3773641578b0d914e61104
Switched from x86_64 to RISC-V because RISC-V is a cleaner and simpler
architecture and I'm more familiar with it since it's similar to MIPS.
BREAKING CHANGE: Switched from x86_64 to RISC-V
feat: Initial parsing of instructions2026-03-14T22:44:18ZJacob McDonnelljacob@jacobmcdonnell.com2026-03-14T22:44:18Zurn:sha1:0c81ee06d19d1d7f67dab3c2c9da268b0c55e3c0
Initial ability to parse basic instructions. Currently hex numbers are
broken and immediates with labels (movl $str, %ecx) are broken.
