Struct GasVersion 

pub struct GasVersion {
    pub major: u32,
    pub minor: u32,
    pub patch: u32,
}

The GNU assembler release claimed, which is the number at the end of what -Wa,--version prints.

This compiler has no separate assembler, but build systems ask for one’s version all the same. The Linux kernel’s scripts/as-version.sh runs $(CC) -Wa,--version and stops the build with “unknown assembler invoked” unless the first line starts with GNU assembler and ends with a version, which Kconfig then compares against the binutils release a feature needs. What does the assembling is rucc-asm, so the claim is about which gas this is meant to stand in for.

2.46 by default, which is the binutils release that was current when GCC 16 came out, and GCC 16 is what GnucVersion claims by default. A build that claims an older GCC with -fgnuc-version= will usually want an older assembler too, and -fgnu-as-version= says so. spec/04-driver-and-cli.md section 4.9 has the rest.

Fields

major: u32

The major number, which is 2 for every binutils release a build is likely to ask about.

minor: u32

The minor number, which is what moves from one binutils release to the next.

patch: u32

The point release, which binutils rarely has and prints only when it is not zero.

impl Eq for GasVersion

impl FromStr for GasVersion

fn from_str(text: &str) -> Result<GasVersion, String>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,
