The rc7 change log talks about DWARF v2 versus v4 incompatibilities:
1.3-rc7 (20191129) - released LLVM/Clang 8.0 toolchain built on stable LLVM branch * UT700/UT699E support with errata work-arounds * REX support: LEON-REX backend (16-bit ISA) added * various LEON optimizations included - Toolchains (GCC and LLVM/Clang) now defaults to DWARF4 debug information, previously DWARF2 was used. GDB-6.8 used with older tools (GRMON2, TSIM2) was not capable of always reading the GCC-7 generated DWARF2 codes and had no support for DWARF4. Enabling DWARF4 makes it possible to perform source level debugging with GDB-8.2.1 which is supported by the newer tools (GRMON3, TSIM3). To use RCC-1.3-rc7 with older tools and GDB-6.8, the binaries should either 1) be stripped, or 2) rebuilt forcing DWARF2 debug format (-gdwarf-2). Build- scripts for Newlib and RTEMS kernel are available in /src directory. - Updated RCC to RTEMS kernel to 20191023: * Updated RTEMS kernel to commit d2efc968e2f644512062de1e06fab20abd2e6854 * Updated Newlib to commit 6661a67747c14cfa7ac91458914037ee296fcd1e * Updated rtems-tools to commit 12bd8f77bad4779319039fd7be33d006e10f5618 - Fixed samples build issues on GCC - GRCANFD IP support: extended GRCAN driver with support for new IP and added new sample in rtems-grcanfd.c. - Restructured GRCAN and OCCAN drivers to depend on a new common CAN baud-rate calculator that includes support for CANFD can standard CAN baud-rate generation. - RTEMS fix for SMP start-up race condition seen when booting from ROM. - Support for having custom GPTIMER pre-scaler setting (was fixed to 1MHz) - Fixed boot issue on LEON3 where GPTIMER initialization depends on previous GRMON initialization. - Support for variable GRETH DMA table size (latest GRETH IP required). - Removed some dependency - Old GRSPW driver: fix for SET_PACKET_SIZE (driver is depreacted and will be removed in the future) - Added precompiled leon3v7 BSP for FPGA designs.
