Alex Richardson	e564932842	[ELF] Write R_RISCV_IRELATIVE addends with -z rel ... I found this missing case with the new --check-dynamic-relocation flag while running the lld tests with --apply-dynamic-relocs enabled by default. This is the same as D101452 just for RISC-V Reviewed By: MaskRay Differential Revision: https://reviews.llvm.org/D101454	2021-07-09 10:41:40 +01:00
Fangrui Song	ee9a251caf	[ELF] Set DF_1_PIE for -pie ... DF_1_PIE originated from Solaris (https://docs.oracle.com/cd/E36784_01/html/E36857/chapter6-42444.html ). GNU ld since https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=5fe2850dd96483f176858fd75c098313d5b20bc2 sets the flag on non-Solaris platforms. It can help distinguish PIE from ET_DYN. eu-classify from elfutils uses this to recognize PIE (https://sourceware.org/git/?p=elfutils.git;a=commit;h=3f489b5c7c78df6d52f8982f79c36e9a220e8951 ) glibc uses this flag to reject dlopen'ing a PIE (https://sourceware.org/bugzilla/show_bug.cgi?id=24323 ) Reviewed By: psmith Differential Revision: https://reviews.llvm.org/D80872	2020-06-01 10:19:41 -07:00
Fangrui Song	71e2ca6e32	[llvm-objdump] -d: print `00000000 <foo>:` instead of `00000000 foo:` ... The new behavior matches GNU objdump. A pair of angle brackets makes tests slightly easier. `.foo:` is not unique and thus cannot be used in a `CHECK-LABEL:` directive. Without `-LABEL`, the CHECK line can match the `Disassembly of section` line and causes the next `CHECK-NEXT:` to fail. ``` Disassembly of section .foo: 0000000000001634 .foo: ``` Bdragon: <> has metalinguistic connotation. it just "feels right" Reviewed By: rupprecht Differential Revision: https://reviews.llvm.org/D75713	2020-03-05 18:05:28 -08:00
