Clang

“for each individual user defecting to clang must be looking very attractive right now”

“Most of the proprietary compilers have been slinking away from using EDG to using clang”

“Some compilers are better than others (Clang>MSVC for example)”

“the language extensions Apple and Google have been adding to clang”

“clang is driving C extensions for safety that should have long been part of the language”

“their mutually compatible, but completely standards non-conformant extensions that make writing for embedded reasonable”

“Another issue I've had with strict conformance in gcc/clang even with regular C is that it will always replace #include with its own copy”

“clang is generating kind of crap code here, and this change gets good codegen out of clang”

“in gcc and clang one must use "-ffp-contract=fast", for enabling FMA instructions.”

“there is even a bug report from QEMU to Clang because it failed to optimize in -O0”

“If you passed the actual '__m128' down the function call chain instead, clang and gcc would then do the right thing.”

“Clang is better than anything I have used in terms of the amount of options and features it has and also how polished it is”

“C compilers just have everything you can think of because everythin is first implemented there.”

“For low runtime footprint you are probably better off with one of those two compilers”

“The facility doesn't seem to have really gone anywhere even if it technically works; I wonder why.”

“Clang also complains about perfectly legal compound IF statements and/or complex IF conditions”

“They should adopt maintenance of clang and bless it as the reference compiler.”

“With modern Clang there really isn't a justifiable reason to use MinGW”

“you even still get (mostly complete) MSVC ABI-compatibility if you compile with clang”

“Clang is the better alternative to MinGW because it can use standard Windows libraries”

“Out of the 6 pieces of Assembly code in the article, 2 of them are definitely inefficient”

“both compilers have done quite heroic and spectacular jobs of optimizing code”

“Clang pretty readily sees that it can use SIMD instructions and really optimizes this”

“It was a cross-platform project and worked equally well with GCC, Clang and MS Visual C++.”

“Clang's solution (presented at the end of the Wikipedia article you linked) seem much better”

“writing zeros to memory (which are never used thereafter), there's no way that particular code is optimal”

“GCC and Clang are worth much much more because they are battle-tested compilers that we understand and know work, even in a multitude of corner cases, over decades.”

“That feels like the right abstraction and it was very easy to set up a VPN with zerotier like that”

“Clang and gcc do a lot of the heavy lifting regarding optimisation”

“sooner or later one will need both `clang` and `gcc`, because they're equivalent only in theory”

“So far I think using clang instead of MSVC compiler is a strict win?”

“Clang is far less ideology-focused and its structure makes implementing optimisations easier”

“Maybe they are not the right solution, but they are working on the right problem.”

“Clang is the better model because it results in more innovation and more software that I can enjoy”

“I like that you can at least compile Linux with Clang and GCC”

“in normal C++ there are GCC or Clang (I forget which) extensions for detecting threading issues”

“I find gcc and clang can inline functions, but can't decide to break apart a struct”

“I was pleasantly surprised by the autovectorization quality with recent clang at work a few days ago.”

“Clang has a lot of footguns, and filing bugs about "regression compared to GCC" does not actually get them fixed.”

“You really shouldn't be using Clang in production because it has all sorts of hard limitations”
