[LLVMdev] Add Support For .bss Named Section Directive For Darwin Targets
Hi - I've attached a patch to make the assembly parser recognise the .bss directive on Darwin targets as a switch to the (__DATA,__bss) section. The ELF & COFF assembly parsers already recongnise the .bss directive. I've added a test case for it too. Thanks - Nick -------------- next part -------------- A non-text attachment was scrubbed...

[LLVMdev] Add Support For .bss Named Section Directive For Darwin Targets
Is this an extension to what cctools' assembler provides or a missing feature in MC?

[LLVMdev] Add Support For .bss Named Section Directive For Darwin Targets
I believe it's a feature missing in MC - https://github.com/opensource-apple/cctools/blob/4da58fd2fc026317ed9e9ef1feabf21ed0bb7a81/cctools-836/as/i386.c line 539 adds support for the .bss directive if certain variables are defined, and mainline gas supports it on all ARM targets: https://sourceware.org/binutils/docs/as/ARM-Directives.html . Supporting the directive on all Darwin targets could be considered an extension though.
