[GSoC] Question about Relatively Simple Library Traits

Hi, I am working on the GSoC project, "C++: Implement compiler built-in traits for the standard library traits". I found the following library traits that I am not sure if implementing built-in traits brings reasonable speed up. * std::is_fundamental * std::is_arithmetic * std::is_scalar * std::i

The macro STACK_BOUNDARY may overflow

Hi, Currently, the macro STACK_BOUNDARY is defined as Macro: STACK_BOUNDARY Define this macro to the minimum alignment enforced by hardware for the stack pointer on this machine. The definition is a C expression for the desired alignment (measured in bits). This value is u

Building gcc-12 on MacOS Ventura (aarch64)

Hi, I am sorting out some issues building RTEMS on MacOS including the M processors. The building gcc-12.2.1 for the few architectures I tested fail with sig faults in xgcc when building the runtime. I tried arm, aarch64 and sparc. As a result I wondered about bootstrapping gcc and using that to b
