Re: [Tinycc-devel] RE : RE : Rewrite of gfunc_call on arm

Are you sure?

After a fresh tcc install

I see you changes:
case R_ARM_PLT32:
            {
                int x, is_thumb, is_call, h, blx_avail, is_bl, th_ko;
                x = (*(int *) ptr) & 0xffffff;

And others from "Allow thumb transition for R_ARM_PC24", yet I still have 
segfault:

------------ abitest ------------
./abitest-cc lib_path=.. include="../include"
ret_int_test... success
ret_longlong_test... success
ret_float_test... success
ret_double_test... success
ret_longdouble_test... success
ret_2float_test... Segmentation fault
make[1]: *** [abitest] Error 139

Also fixed. For the curious, bl to blx conversion was only made for R_ARM_CALL 
relocation while it's also possible for R_ARM_PC24 relocation when the 
instruction being relocated is an unconditional branch and link (bl).
