Yes - the gcc "torture test suite" that is mentioned must have been one of the enablers for this.

It's notable that the article says Claude was unable to build a working assembler (& linker), which is nominally a much simpler task than building a compiler. I wonder if this was at least in part due to not having a test suite, although it seems one could be auto generated during bootstrapping with gas (GNU assembler) by creating gas-generated (asm, ELF) pairs as the necessary test suite.

It does beg the question of how they got the compiler to point of correctness of generating a valid C -> asm mapping, before tackling the issue of gcc compatibility, since the generated code apparently has no relation to what gcc generates. I wonder which compilers' source code Claude has been trained on, and how closely this compiler's code generation and attempted optimizations compares to those?

i'm sure claude has been trained on every open source compiler
