I am looking for a tool to simplify analysing a linker map file for a large C++ project (VC6). During maintenance, the binaries grow steadily and I want to figure out where it comes from. I suspect...

I was looking at the different instructions in assembly and I am confused on how the lengths of different operands and opcodes are decided upon. Is it something you ought to know from experience, ...

I am developing a C++ for ARM using GCC. I have ran into an issue where, I no optimizations are enabled, I am unable to create a binary (ELF) for my code because it will not fit in the available sp...

/* The following codes are compiled into library(test.a) */ typedef struct { short x[5]; } weight_t; typedef struct { weight_t wgt; char *ptr; } tbl_t; /* huge static array and 70% of entries ...

/* The following codes are compiled into library(test.a) */ typedef struct { short x[5]; } weight_t; typedef struct { weight_t wgt; char *ptr; } myarray_t; /* huge static array and 70% o...

I was reading this question because I'm trying to find the size of a function in a C++ program, It is hinted at that there may be a way that is platform specific. My targeted platform is windows T...

Is there any maximum size for code in Java? I wrote a function with more than 10,000 lines. Actually, each line assigns a value to an array variable. arts_bag[10792]="newyorkartworld"; arts_bag[1...

When I watch demoscene videos on youtube the author's often boast of how their filesizes are 64kb or less, some as few as just 4kb. When I compile even a very basic program in C++ the executable is...

What would be the shortest Intel x86-64 opcode for setting rax to 1? I tried xor rax,rax and inc al (in NASM syntax); which gives the 5-byte opcode 48 31 c0 fe c0. Would it be possible to achieve ...

From Effective C++ by Scott Meyers: template<typename T, std::size_t n> class SquareMatrix: private SquareMatrixBase<T> { public: SquareMatrix( ) : SquareMatrixBase<T>(n, 0)...

I've read quite a few posts about the use of static inline and inline while defining functions in header files for access across multiple translation units. It seems like inline is the right way to...

I compared the languages at the language shootout game by their code size only. Here is a summary of what I got (shortest first, grouped by similar score). Python, Ruby, JavaScript, Perl, Lua, PH...

Why doesn't cabal install use the flag --enable-shared by default? I've notice that trivial programs when compiled without this flag, get huge in file size. Is there a connection? Is this a design ...

I have a huge number of functions totaling around 2.8 GB of object code (unfortunately there's no way around, scientific computing ...) When I try to link them, I get (expected) relocation truncate...

My iPhone app is getting ready to go to production and we like to cram in as much data as possible. When I poke around the generated .app file for my application I see a file named <executable n...

This question was asked here before, but none of the answers really tried to answer the actual question asked, so I'm asking it in a different way. Is loading a single class of 20,000 lines with 10...

Many people have argued about function size. They say that functions in general should be pretty short. Opinions vary from something like 15 lines to "about one screen", which today is probably abo...

I have a C++ library that generates much larger code that I would really expect for what it is doing. From less than 50K lines of source I get shared objects that are almost 4 MB and static archive...
