Re: [Tinycc-devel] gcc/tcc nested macros difference

[Christian Jullien]

Do you known that you can test C/C++ code using different gcc/clang version
on
http://gcc.godbolt.org/

As you type your code on left window it displays assembler code on the
right. You can of course play with different options to see how it modifies
generated code.
You can even make a link to share your experience with others.

A must have when you try to optimize some code.
Last but not least, it support ARM 32/64.

If you suspect something wrong with tcc please add a test there and show us
wrong behavior compared to gcc.

Enjoy!

C.

> Look at the __ie16_to_cpu presence in the tcc output: nested macro was
not expanded

But if we define le16_to_cpu with arg, i.e -#define le16_to_cpu
__le16_to_cpu
+#define le16_to_cpu(x) __le16_to_cpu(x)

then tcc output is OK. I used gcc 3.4.6 and 4.1.2 to test. May be new
versions of the gcc behave like tcc.
