## Compiler {#compiler} The compiler and linker in Go 1.25 now generate debug information using [DWARF version 5](https://dwarfstd.org/dwarf5std.html); the newer DWARF version reduces the space required for debuging information in Go binaries. DWARF 5 generation is gated by the "dwarf5" GOEXPERIMENT; this functionality can be disabled (for now) using GOEXPERIMENT=nodwarf5. ## Assembler {#assembler} ## Linker {#linker}
