...ource tree. But if we use the inline script version - the right version is embedded in the binary & available every time. This gets a bit ugly - writing Python inside inline asm isn't really comfortable (even with C++ raw string literals to get past one level of escaping), but we could use incbin assembler directive to include a Python source file straight into the inline asm in the right place. Only problem: Clang's incbin support is buggy <http://llvm.org/PR24811> in a way that makes this not work (disabling the integrated assembler does demonstrate this working successfully)....

I'm running into some pretty bad performance in llc.exe when compiling some large neural networks into code that contains some very large llvm::ConstantDataArrays, some are { size=102,760,448 }. There's a small about of actual code for processing the network, but the assembly is mostly global data. I'm finding that llc.exe memory spikes up around 30 gigabytes and the job takes 20-30

One of the issues I reported in using lld as the FreeBSD base system linker is that the base system currently uses ld -r to convert a binary file (device firmware image) into an ELF object: > A tool for loading firmware into a wireless USB device includes a > built-in copy of the firmware image, and the image is converted to an > ELF file using ld -r. The invocation is: ld -b binary -d
