The GCC 4.6 release series differs from previous GCC releases in more than the usual list of changes.Some of these are a result of bug fixing, and some old behaviors have been intentionally changed in order to support new standards, or relaxed in standards-conforming ways to facilitate compilation or runtime performance.

WebSep 19, 2014 · But if we don't know which pointer is greater, it gets more complicated: To do correct short* pointer subtraction, we need to subtract pointers using sub %edx, %eax; rcr $1, %eax --- i.e. shift the carry bit back to the topmost bit of the result. According to Agner's tables, rcr with 1-bit count takes 1 tick on AMD and 2 ticks on Intel, so the ... stanton kings cross

WebActually it is worse than you think. The problem is __PTRDIFF_TYPE__ is defined incorrectly if pointers can span across the sign bit (32bit). There is whole thread about this on gcc@. The C/C++ language defines ptrdiff_t as a type which can be used two take a difference of any two valid pointers and get a signed difference. WebThis can be used to implement struct packing on MS Visual C compilers, see the Win32 port in the lwIP contrib repository for reference. For examples of packed struct declarations, see include/lwip/prot/ subfolder. A port to GCC/clang is included in lwIP, if you use these compilers there is nothing to do here.
