> This is a part I missed, because I do not have an Xcode toolchain at hand, so thanks for investigating. However this, in my opinion, is a flaw with Mach-O/mtoc and not with my patch. It seems like the only difference between __TEXT,__const and __DATA,__const is whether the data is targeted by a relocation or not. Such a concept does not exist for PE/COFF (and I think not even for ELF, but I'm not too familiar with it), thus the logical PE/COFF section __DATA,__const should be merged into is .rdata (and .rdata may or may not be merged into .text in an earlier step, I assume transitivity). I could change the macro definition to explicitly declare __TEXT,__const, but that would still put the compiler-emitted data in the wrong section. Does Xcode provide anything remotely similar to GNU linker scripts which we can use to move the section?

> Please also note that .rodata is used for Xcode-based toolchains already (in fact, all toolchains, and this is the issue), I'm not regressing anything. I just expected it to work fine as-is. This patch mainly fixed PE/COFF-based toolchains, which get both .rdata from the compiler and .rodata with RX permissions from NASM, because ".rodata" only has a semantic meaning for ELF and Mach-O outputs, but not for PE/COFF.

The Xcode linker emits a fatal error on X64 for a relocation in the __TEXT section, everything needs to be RIP relative and the compiler does that for free. We generally only run into this for hand coded assembler and the fix is to use RIP relative addressing in the assembly.

OK so the current nasm `SECTION .rodata`[1] gets mapped to __TEXT,__const[2] for Xcode clang, and this is done by nasm (I dumped the object file). GenFw and mtoc only run on executables, also they tend to be conservative as they need to keep the layout the same and the relative layout between sections the same, but in this case it is nasm placing the data in the text section.
So what I’d like to see in the patch is to define RODATA_SECTION_NAME to match what is actually happening. So for XCODE that would be `__TEXT,__const` not `.rodata`. We should double check what is happening for ELF on x86, ARM, RiskV, etc. and do the same thing. I assume all the tools that generate PE/COFF directly are good with .rodata? I think it is likely as simple as dumping the EFL object file in objdump or gdb for the given toolchain (like my Xcode example).
TL;DR It looks to me like nasm does some SECTION translations under the hood to make code portable, and I’d like to make sure we capture those in the new NASM_RODATA_SECTION_NAME. If some one is doing a security review having NASM_RODATA_SECTION_NAME is going to imply that a .rodata section is being used by that specific toolchain, and I think that is much worse than the current “magic” behavior in nasm. We are much better off explaining what is really happening, since it is not very obvious.
