2018-06-21RISC-V: Add custom RTEMS multilibsSebastian Huber
Add multilib variants for -march=rv64imafd, e.g. to support the BOOMv2 core. Add -mcmodel=medany as a variant of the 64-bit multilibs for RTEMS. The rationale for this change is that several existing RISC-V chips map the RAM at 0x80000000. In RTEMS, we do not use virtual memory, so applications will run at this location which is outside the +-2GiB range in a 64-bit configuration. gcc/ * config.gcc (riscv*-*-elf* | riscv*-*-rtems*): Use custom multilibs for *-*-rtems*. * config/riscv/t-rtems: New file. git-svn-id: https://gcc.gnu.org/svn/gcc/branches/gcc-7-branch@261838 138bc75d-0d04-0410-961f-82ee72b054a4

2018-06-19xtensa: fix PR target/65416Max Filippov
The issue is caused by reordering of stack pointer update after stack space allocation with instructions that write to the allocated stack space. In windowed ABI register spill area for the previous call frame is located just below the stack pointer and may be reloaded back into the register file on movsp. Implement allocate_stack pattern for windowed ABI configuration and insert an instruction that prevents reordering of frame memory access and stack pointer update. gcc/ 2018-06-19 Max Filippov <jcmvbkbc@gmail.com> Backport from mainline 2018-06-19 Max Filippov <jcmvbkbc@gmail.com> * config/xtensa/xtensa.md (UNSPEC_FRAME_BLOCKAGE): New unspec constant.

2018-06-14RTEMS: Prefer int for int32_tSebastian Huber
Common systems like glibc and FreeBSD define int32_t to int. This means a lot of third party code works well in these cases: #include <stdint.h> void f(int32_t); void f(int); void g(int32_t *); void h(void) { int i; g(&i); } On RTEMS you got however in C test.c:5:6: error: conflicting types for 'f' void f(int); ^ test.c:3:6: note: previous declaration of 'f' was here void f(int32_t); ^ test.c: In function 'h': test.c:12:4: warning: passing argument 1 of 'g' from incompatible pointer type [-Wincompatible-pointer-types] g(&i); ^ test.c:7:6: note: expected 'int32_t * {aka long int *}' but argument is of type 'int *' void g(int32_t *); and C++ test.c: In function 'void h()': test.c:12:4: error: invalid conversion from 'int*' to 'int32_t* {aka long int*}' [-fpermissive] g(&i); ^~ test.c:7:6: note: initializing argument 1 of 'void g(int32_t*)' void g(int32_t *); ^ This was due to a Newlib speciality which uses long for int32_t if long is a 32-bit type. To ease the use of third party software in RTEMS we override this Newlib option now and use int for int32_t if int is a 32-bit type. gcc/ * config/rtems.h (STDINT_LONG32): Define. git-svn-id: https://gcc.gnu.org/svn/gcc/branches/gcc-7-branch@261584 138bc75d-0d04-0410-961f-82ee72b054a4
