Bug 22083 – Error: function ldc.intrinsics.llvm_bswap!uint.llvm_bswap conflict with std.bitmanip.nativeToBigEndian!ushort.nativeToBigEndian

kinke think this is a frontend bug, only showing in LDC: https://github.com/ldc-developers/ldc/issues/3772 ================================================= Hi, While building apache-thrift, LDC has build failure (DMD succeed): /home/./.dub/packages/apache-thrift-0.14.1/apache-thrift/lib/d/src/thrift/transport/websocket.d(335,39): Error: function ldc.intrinsics.llvm_bswap!uint.llvm_bswap at /home/./project/ldc2-1.26.0-linux-x86_64/bin/../import/ldc/intrinsics.di(405,7) conflicts with function std.bitmanip.nativeToBigEndian!ushort.nativeToBigEndian at /home/./project/ldc2-1.26.0-linux-x86_64/bin/../import/std/bitmanip.d(2998,6) While there is a work around by using fully qualified names: std.bitmanip.nativeToBigEndian, I think LDC compiler should be fixed. $ ldc2 --version LDC - the LLVM D compiler (1.26.0): based on DMD v2.096.1 and LLVM 11.0.1 built with LDC - the LLVM D compiler (1.26.0) Default target: x86_64-unknown-linux-gnu Host CPU: znver1 http://dlang.org - http://wiki.dlang.org/LDC This looks like a frontend bug - the conflict seems to be caused by https://github.com/ldc-developers/phobos/blob/16d1a9be59cb319961bd7bc0bcd1128151fc0a67/std/digest/sha.d#L124, ``` version (LittleEndian) { private alias nativeToBigEndian = bswap; private alias bigEndianToNative = bswap; } ``` which is a private alias, which - for LDC - aliases 2 other aliases: https://github.com/ldc-developers/druntime/blob/8916695501005be33291f5a88e399b7eb1eb9e25/src/core/bitop.d#L657 and ``` version (LDC) { alias bswap = llvm_bswap!uint; } ``` https://github.com/ldc-developers/druntime/blob/8916695501005be33291f5a88e399b7eb1eb9e25/src/core/bitop.d#L677 ``` version (LDC) { alias bswap = llvm_bswap!ulong; } ``` ================================= I wasn't able to reduce it to a smaller test case; maybe someone who is more familiar with the frontend code can do.

Might be related to https://issues.dlang.org/show_bug.cgi?id=21829.

This issue could have a simple fix for someone who knows it. Is there anyway to escalate this issue? Thanks.

I suppose it happens in ldc because llvm intrinsic is used only in ldc, try to replace it with a nonintrinsic function.
