Hi All, Congratulations on the major progress on the llvm linker lld over the past year including the new linker script support. This really makes it possible to ditch binutils altogether. It looks like lld's MEMORY sections are currently parsed but not evaluated, but so far that hasn't been a problem. The only snag is I can't figure out how to define the start of the .data section

Hi All, Clang lacks support for the -fsingle-precision-constant flag. Are there specific reasons for this or is it just waiting to be implemented? This flag is especially important in the embedded world. From http://processors.wiki.ti.com/index.php/Floating_Point_Optimization#float_vs._double_vs._long_double : *Once all of your data is defined as float, there are still cases where you may

Thanks for the response. If we add the support would you accept the patch? Seems like a pretty straightforward flag since it maps directly to NumericLiteralParser::NumericLiteralParser within LiteralSupport.cpp. I understand the maintenance concern with flags that affect multiple points in code though. Still trying to get the bottom of why we're crashing with double floating point literal.

Hi All, After the initial learning curve, we're excited to have put together a completely gcc/binutils-free toolchain based on LLVM. Now that we have things working, we desperately need to optimize the resulting binaries. Our bin files are up to 10x their fully optimized gcc equivalent (1.5k vs 16k). This is for a bare metal ARM based system so this is significant. We're using lld for
