"error: expected string in directive" on ARM #744
Comments
upstream bug: https://llvm.org/pr43759 differential: https://reviews.llvm.org/D69296 |
interesting, which source file does this occur in, @jcai19 ? |
It's in arch/arm/mm/proc-v7.S. $ ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j32 CC=clang AS=clang arch/arm/mm/proc-v7.o AS arch/arm/mm/proc-v7.o I have a local patch that seems to fixes the "expected absolute expression" errors at #742 (still trying to figure out the right unit test before sending it for review), but to be able to build this file with integrated assembler, we also need to fix the this error (the last one). |
Based on smithp35's comment, if the Linux kernel is currently the only instance the Solaris style comment markers are used, I suggest that we postpone D69296 until there are more instances and we get to the point that not implementing it can cause more trouble. |
There are more updates to the code review so hopefully this will not be a concern. |
It sounds like we should patch the kernel in this case. Is there a syntax that is not "solaris style" that we should use? |
That would be great. We can use "a" to replace #alloc (https://sourceware.org/binutils/docs/as/Section.html). FYI it was mentioned in D69296 there are more usage of such syntax besides Linux. |
sounds like this was reverted. |
We could send a kernel patch. Looks like there's 28 instances of it throughout arch/arm/. |

It looks like a section directive was using "Solaris style" to declare the section flags. Replace this with the GNU style so that Clang's integrated assembler can assemble this directive.
