How to access both the source and target programs in gcc at the same time

+1 vote
71 views

I need to access in-memory representation of both the source program(the program before compilation) and target program(the program after compilation) at the same time. If I add a plugin between two passes,say p1 and p2, I will be able to access the program produced by only p1 but I would neither be able to access the program which was before executing p1 nor the program after p2. I want to compare the programs before and after compilation. How to do that?

I have ported the GCC (v4.5.3) to a new target (32-bit RISC processor). So far everything went fine. I wrote my own little C-Lib with basic input output and tested it worked. Until today I never actually tried optimization passes (maybe that was the mistake that lead to this)
Anyway:
During porting and building Newlib I ran into an error that I tracked down to the following code:

unsigned char hexdig[256];

static void htinit ( unsigned char *h , unsigned char *s , int inc)
{
 int i, j;
 for(i = 0; (j = s[i]) !=0; i++)
 h[j] = i + inc;
}

void
hexdig_init ()
{
 htinit(hexdig, (unsigned char *) "**********", 0x10);
 htinit(hexdig, (unsigned char *) "abcdef", 0x10 + 10);
 htinit(hexdig, (unsigned char *) "ABCDEF", 0x10 + 10);
}

Compiling this code without optimization works like a charm, however compiling it with -O2 leads to the following error:
test1.c: In function 'hexdig_init':
test1.c:11:1: internal compiler error: in gen_lowpart_general, at rtlhooks.c:59

Tried with:
eco32-gcc -O2 -S test1.c

My question in short is:
Could this be a targe- backend-error or just some configuration I have missed while building GCC?
Any pointers into the right direction are welcome.

We are trying to build our code base for CentOS 7 machine with x86_64 architecture on CentOS6 with x86_64.

For that we are trying to build a centos7 Toolchain. All the gcc/ld/ar should be statically linked, so that we are ensuring that it will not uses any native centos6 stuff.

In this process, we are able to generate statically linked GCC/AR/LD. But problem was this GCC not generating a statically linked binaries and fails while checking flags during configure at "checking static
flag -static ". Due to this while running those binaries it refers to native libgcc and fails.

We are using the below command for configure.

../gcc../configure -prefix=/mnt/data0/toolchain-vm-temp2 --build=x86_64-CentOS7-linux-gnu-with sysroot=/mnt/data0/tools/gnutools/toolchain-vm --disable-nls --disable-multilib --enable-languages=c,c++ --disable-sim --enable-symvers=gnu --enable__cxa_atexit --enable-lto --with-gnu-ld --enable-static

Can Anyone provide solution or how to achieve this task.

I wanted to ask what is the GCC C++ equivalent implementation of Windows _ MyFirst and _MyLast vector pointers?

These give direct access to the vectors first and last element, but they are not present in the GCC implementation of the vector class.
