Perhaps, but not because inlining would be done now: it isn't. TCC
doesn't inline functions into others. But due to how c99 and c11 have
special requirement for functions marked "inline" the keyword isn't
completely ignored either, but it still doesn't cause called functions to
be integrated into their callers.
Inline asm is something else (and doesn't use an "inline" keyword
anyway), it simply describes the fact that you can write assembler
instructions in C files, "in line" with the C sources, and don't have to
resort writing .s files.
Ciao,
Michael.

Yet it officially supports inlined assembly, that also uses the
'inline' keyword, hence not completely "ignored".
Anyway, if you look at the tcc source code (tccgen.c, tccpp.c,
...) there is already plenty of "inline" inside.

Have I missed anything?
The documentation for TCC 0.27 states that the inline keyword is
ignored

[Tinycc-devel] How exactly inline works and should I inline all the time?
Hi! I don't know if we must only post questions that are specific to the TCC compiler specifically (even tho this question can differ from compiler to compiler) or we can make questions about C in general and in the case that the first is true then please inform me so I know. Anyway I wanted to ask how inline works specifically and not generally. I know generally that it "puts the source code" inline so we don't have to use "jmp" but is there anything else to it that I should know? Are there any dangers or reasons than someone should not use it? Also is there a way to tell the compiler to inline every function rather than always having to add the "inline" keyword? ___ Tinycc-devel mailing list Tinycc-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/tinycc-devel
