I would prefer directly using the __ARM_NR_cacheflush syscall to make it work on non-Bionic Linux as well. The syscall has been introduced into Linux in 2.3.7pre6. Glibc uses it in libdl after perfoming relocations since 2005 and according to https://github.com/android/platform_bionic/blob/master/libc/arch-arm/syscalls/cacheflush.S it is what Bionic's cacheflush uses under der hood. Unfortunately it is not exposed by Glibc. Daniel ___ Tinycc-devel mailing list Tinycc-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/tinycc-devel

Ignore my previous message...bionic libc doesn't have strtold. Back to the drawing board...

Re: [Tinycc-devel] Problem Compiling tinycc For Android: strtold
Just saw your email as I was getting ready to post my next questions. 1) should I just find/replace in the code or make an alias to strtod? 2) Android's version of __clear_cache is cacheflush, can I make an alias for that as well?

Re: [Tinycc-devel] Problem Compiling tinycc For Android: strtold
I suspect you're right...now off to find out where that particular option goes... (still grepping my way through pages of gcc documentation and Android internals) Will the same work for __clear_cache? I suspect not, based on a cursory examination of that and cacheflush, but I'd be happy if someone corrected me.

Re: [Tinycc-devel] Problem Compiling tinycc For Android: strtold
I couldn't figure out how to correctly use -Dstrtold=strtod, so I did a simple find/replace to test build. It worked, but I would like to do this correctly. I did a search on -D, Makefiles, -D gcc options and grepped for D within the source directory. I couldn't find/see anything that resembled the original suggestion but I did find a lot of articles on overriding a library during compile or with weak aliases. What is the standard way for making one function a reference to another in a different header? Also, would that work for linking __clear_cache to the Android equivalent cacheflush?
