Douglas Raillard 0c62883f7e backtrace: Introduce backtrace function This function diplays the backtrace, the current EL and security state to allow a post-processing tool to choose the right binary to interpret the dump. The output can be fed to GNU addr2line to resolve function names given an ELF binary compiled with debug information. The "-i" flag is recommended to improve display in case of inlined functions. The *.dump files generated during the build process can also be used. The function works in AArch64 and AArch32. In AArch32 it only works in A32 mode (without T32 interworking), which is enforced in the Makefile. Sample output of a backtrace at EL3: BACKTRACE: START: function_name 0: EL3: 0x798 1: EL3: 0x538 2: EL3: 0x550 3: EL3: 0x55c 4: EL3: 0x568 5: EL3: 0x5a8 6: EL3: 0xf4 BACKTRACE: END: function_name In order to enable it the new option ENABLE_BACKTRACE must be set to 1. This option is set to 1 by default only in AArch64 debug builds. As usual, it can be overridden by the platform makefile and in the build command line.
