--- Comment #7 from Jim Wilson <wilson at gcc dot gnu.org> --- An empty linker script isn't expected to work. This will probably fail for every linker target. It fails for x86_64-linux for instance. rohan:2037$ uname -a Linux rohan 4.15.0-47-generic #50-Ubuntu SMP Wed Mar 13 10:44:52 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux rohan:2038$ gcc -Ttmp.ld tmp.c /usr/bin/ld: a.out: Not enough room for program headers, try linking with -N /usr/bin/ld: final link failed: Bad value collect2: error: ld returned 1 exit status rohan:2039$ The linker shouldn't crash, but you've done something funny here though. You are either using a non-standard gcc or non-standard gcc options, which have enabled some kind of consistency checking support. Since you haven't explained what you did, I am unable to reproduce the failures you are seeing. You also have non-standard libraries which appear to conflict with the published RISC-V psABI. This also prevents me from reproducing the failures you are seeing.

They are standard for MIPS toolchains, and any toolchain that uses MIPS style ABI conventions. There are about half a dozen of them in GNU ld, including RISC-V. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
