Fixed two issues with the "nognu" file: - one instance is enough (in /share/ncc/) - the NOGNU macro should be properly defined

Initial import of ncc: ncc is a compiler that produces program analysis information. ncc is a decent replacement of cflow and cscope able to analyse any program using the gcc compiler. The program also incliudes a graphical call-graph navigator and source browser which is extremely practical for hacking and comprehending large projects. Does someone find this useful?

Update ncc to version 2.7 Changes since 2.1: New in 2.7 ========== - In the case where in a Makefile we had a target like: gcc foo.c bar.c zoo.c -o program using ncc instead of gcc would fail. Now this case is handled correctly. If -ncgcc is specified gcc will be executed as above. ncc instead will analyse each file and then link the generated .nccout files to program.nccout. (qemu) - Fixed leaving ncurses mode -> xterm -> re-enter ncurses in nccnav. Patch by Sylvain Beucler. - New command line option -nccpp=<preprocessor>, useful for using ncc in cross compilation, from Jose Vasconcellos New in 2.6 ========== - '-m*' flags are passed to the preprocessor. For example if '-mmmx' is not used in preprocessing, the macro __MMX__ is not declared and importing <mmintrin.h> will fail. (X11R71) - If nccnav is executed from the root of the source tree, it will show relative file paths (good). - Updated instructions for kernel hacking. Some object files were missed. - Fixed segfault with __gu_val. - Speed up linking nccout object files. - nccnav crashed if it couldn't open the temporary file. New in 2.5 ========== - The nccnav viewer can show functions and files with "vi", thus with syntax coloring. This will happen if you press 'v' on a function. - The nccnav viewer can start from the list of global variables (by pressing 'g' in the initial screen). - nccar will understand the "r" option and replace members in the archive instead of just appending the data. That's the right thing because with the old version, linking archives into bigger archives would result in geometric explosion of the size of the files. - Better type propagation in conditional expressions. (x ? (void*)0 : (struct A*)a)->x; now works (gcc/LIM_DATA) - support for anonymous structures and unions (GNUC): struct X { union { int a, b, c; } }; void f (struct X *x) { x->a = 1; } (linux 2.17) - Fixes to hack linux 2.17: - The "__typeof__ (function)" can be used to declare another function - forward enum declarations - char X[] = ("hello"); // was error - The expression in a Variable Length Array is not constant (and in fact it can call functions). int X [y = foo()]; // was error - Debian package and Doc fixes by Anuradha Weeraman. New in 2.4 ========== - Bugfix (segfault with gcc 4.x) from Florian Larysch. - More configury for 'alloca()' in dbstree. - new command line option '-ncnoerr'. When there are errors in expressions, ncc will not terminate the compilations. Instead it will link all functions that had errors with the special pseudo-function "NCC:syntax_error()". New in 2.3 ========== - Bugfix (segfault with gcc 4.0) from Deepak Ravi. - a typedef name used as a label would cause a syntax error (JamVM) - Applying '*' on a function has no effect. (pygame) void (*F)(); (**F)(); // used to be error - Support for '_Complex' as a declaration specifier. New in 2.2 ========== - Included a LICENSE text in doc so ncc can be part of Debian. - Bugfix/crash in nccnav. Pressing the up-arrow in functions mode caused a segmentation violation because isalpha(KEY_UP) is true. - if the last statement of a compound statement in expression was an __asm__ and that was the first expression of the program we had a segfault. Thanks to Thomas Petazzoni. - Header file fixes for MacOS. (Adam Shostack) - __inline__ is accepted as 'inline'. gcc-3.4.4 broke things again. - more pointer-to-function cases caught: fptr = flag ? p->tp_call : 0; now detects that calling fptr() may call p->tp_call() (python)
