After the successful small GNFS run, I tried a larger SNFS run with the same binaries, but no luck:

Hello! I have some errors while compile under cygwin: it's like that

cantor/mpfq_2_128.h.32:791:error:invalid operands of types 'long long int _vector_' and 'long long int _vector_' to binary 'operator^'.

anyone know how to fix this error?

When i try to compile cado-nfs from the repository, i get an error at ./utils/cachesize_cpuid.c:47:3. Inconsistent operand constraints in an 'asm'. Does anyone know what this error means or how to fix this? I am using gcc 4.6.3 (Ubuntu/Linaro 4.6.3).

BWetter246 · 2012-06-03, 23:17

ok, so i pretty much changed the cpuid function in cachesize_cpuid.c and it compiled.

Code:

#include <cpuid.h>
void cpuid(uint32_t res[4], uint32_t op) {
  __get_cpuid(op, &res[0], &res[1], &res[2], &res[3]);
}

jasonp · 2012-06-04, 02:04

Looking at the original, it appears that eax is being referenced by name as an input and an output to the asm, which older versions of gcc inline asm syntax allowed but current versions do not. I'll forward the report to Paul's group; it's strange they haven't seen it already.

BWetter246 · 2012-06-04, 16:17

how about this

Code:

void cpuid(uint32_t res[4], uint32_t op) {
#ifdef	__GNUC__
  __asm__ volatile( "pushl %%ebx   \n\t"
                "cpuid         \n\t"
                "movl %%ebx, %1\n\t"
                "popl %%ebx    \n\t"
                : "=a"(res[0]), "=r"(res[1]), "=c"(res[2]), "=d"(res[3])
                : "a"(op)
                : "cc" );
#else
#error "Please teach your compiler how to call cpuid"
#endif
}

Regarding your CPUID substitute, the problem I see is that you have a "=a" in the output list and an "a" in the input list. While the syntax does let you reuse a specific register, I didn't think mentioing it by name twice was allowed. Msieve does something similar:

Code:

	#define CPUID(code, a, b, c, d) 			\
		ASM_G volatile(					\
			"movl %%ebx, %%esi   \n\t"		\
			"cpuid               \n\t"		\
			"movl %%ebx, %1      \n\t"		\
			"movl %%esi, %%ebx   \n\t"		\
			:"=a"(a), "=m"(b), "=c"(c), "=d"(d) 	\
			:"0"(code) : "%esi")

BWetter&jason, thanks for pointing the bug and fix. As jason's post, does it work if we change the input line from

Quote:

: "a" (op)

to

Quote:

: "0" (op)

Btw: I just tested it (without above change) on a Ubuntu 12.04 machine (Ubuntu/Linaro 4.6.3) and it compiles fine. What flag do you use?

BWetter246 · 2012-06-05, 20:43

I used make in bash and it generated -g -W -Wall -O2.
