Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Lazarus IDE 3.0 Released
Sure. It's the section here https://github.com/riscv-non-isa/riscv-elf-psabi-doc/blob/ma...
It's that structs of two simple fields need to be passed in registers. And more specifically that this rule is relevant for mixed integer and floating point fields.
It's a very specific rule that requires a ton of code to implement compared to the integer calling convention. And again like the weird AMD64 convention likely invented to squeeze out a theoretical few cycles that never occur outside microbenchmarks
- Please help!

RISC-V assembler input file format
This one has more info on the ELF output, notably things like how things like relocations and special symbols like %pcrel_hi work: https://github.com/riscv-non-isa/riscv-elf-psabi-doc/blob/master/riscv-elf.adoc

RISC-V assembly example: incrementing each char in a string
This is a bit dense but that's what I referred to https://github.com/riscv-non-isa/riscv-elf-psabi-doc/blob/master/riscv-cc.adoc. I'm not sure if there's a RISC-V specific assembly tutorial that talks about calling conventions.
- RISCV on the rise. Intel joins the bandwagon. Threat or potential for linux gaming?

RV32I Stack and stack pointer in hardware implementation
The stack is defined by the ABI and it’s a purely software convention. It’s possible a program could use a different convention. FYI, the EBI is defined here: https://github.com/riscv-non-isa/riscv-elf-psabi-doc

Support for Extension and CSR detection in ELF and linker/loader?
It looks like people are starting to think somewhat along that direction in https://github.com/riscv-non-isa/riscv-elf-psabi-doc etc. but most CPUs that I can think of have basically a monolithic ISA with pretty much an expanding set of instructions as the versions increment and encoded in the -march argument to the linker.
