Re: question about pic and relocation

But flag '-shared' and '-fpic' are used to create shared object, aren't they? When I use objdump to see the codes, I find that the program address doesn't start from 0. Such as, 5ffe065c : 5ffe065c: 3c02lui v0,0x0 5ffe0660: 27bdffe8addiu sp,sp,-24 5ffe0664:

Hi, Given such a source file, /*fun.c*/ int b=2; void fun(void) { int a=b; } Then compile it, $ mips-elf-gcc -shared -fpic fun.c -o fun.so -save-temps We can see this below from fun.s, lw $2,%gp_rel(b)($28) I think symble 'b' should be of GOT relocation. But it isn't. $ mips-elf-readelf

Hi, I think/thought this has been dealt with but am not sure. I started with a fresh install directory, built and installed a native GNU/Linux C, C++, and Ada toolset. Then proceeded to try to build cross Ada for *-rtems. All targets are failing because they are not finding newlib's .h files

Re: Ada subtypes and base types

When I speak about doing arithmetic in a type, I'm referring to the type of the expression & its input operands in a gimplified expression. At that point I do not care about base types or anything like that. All that should matter is TREE_TYPE (expr), nothing more, nothin
