Maybe try: .set noat AT is needed to create certain instructions from pseudo instructions, so you have to be careful how you use this. Some instructions that you can use in Mips assembler are in fact pseudos. While AT is not available to it (.set noat), the assembler can not assemble certain pseudos for you. On 0...

Which part of the generated code do you think is not correct? Could you be more specific? I compiled this program with clang and ran it on a mips board. It returns the expected result (21).

I check the Mips backend for the following C code fragment compile result. It seems not correct. Is it my misunderstand or it's a bug. //ch8_3.cpp #include <stdarg.h> int sum_i(int amount, ...) { int i = 0; int val = 0; int sum = 0; va_list vl; va_start(vl, amount); for (i = 0; i < amount; i++) { val = va_arg(vl, int); sum += val; } va_end(vl);

Hi David, What kind of "a lot of out-of-tree changes"? You should push changes incrementally as you do work. Holding onto changes means that many things, not just reformatting, can make them need to be redone. We frequently clean up and rewrite code to make it cleaner and easier to maintain. We are moving to a more strict internal review and pushing of changes and post commit

...are specific revisions that you'd like me to clean up and rebase I'd be happy to do so. In particular, we have dsub* and daddi, dli, dla, la, and .cpsetup implemented (although not the most efficient implementation of any of them, hence these patches not being ready for upstreaming), .set noat / at doing the right thing, and have fixed (I think) MIPS IV support (although not yet MIPS III, which is an oversight given that Loongson 2F is MIPS III). > It takes time to review and respond to comments on formatting issues; time that would be better spent doing new work.

Hello, Here is V2 of the arm64 support for klibc patch set. Notable changes since the original series: * fp regs dropped from setjmp/longjmp * chmod, lstat and stat re-implemented with *at functions. * open64 merged into open. As with the original, this series is to be applied against the latest klibc, just after 25a66fa README.klibc: update build information V2 has been tested on x86_64

Hello, This series introduces arm64 support to klibc. I've rebased the work from Neil Williams and Anil Singhar into the following three patches. Most of the code changes are due to new syscall implementations being needed for arm64 as a only a minimal set of syscalls are defined in the arm64 kernel. This series is to be applied against the latest klibc, just after 25a66fa README.klibc:
