i'm doing this in the context of building for ARM with a linaro toolchain, but i'm sure it's equally valid in the context of a native build.
i'm trying to generate the same output as u-boot.map, but more condensed and with each symbol associated with its original source file (if that's even possible). for example, there are a couple weak symbols in board_f.c: __weak int arch_cpu_init(void) { return 0; } __weak int mach_cpu_init(void) { return 0; } so depending on the target board, the final included version of such a routine might come from board_f.c, or it might be overridden at the board level. you can sort of see this in u-boot.map: .text.arch_cpu_init 0x0000000000000000 0x8 common/built-in.o ... .text.mach_cpu_init 0x0000000004011cac 0x8 common/built-in.o 0x0000000004011cac mach_cpu_init except i was hoping to be able to list included symbols by their *original* source file, and listed one file at a time, so the output would have the format: board_f.o mach_cpu_init ... other stuff from board_f.o i could swear i once knew how to do this, but i've forgotten (or perhaps i'm misremembering). is there some variation of objdump, readelf or nm that will do what i want? i need nothing other than, for each source file, the symbols that were included in the final ELF file from that source file. can i do this? rday _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
