Hi all, I have been investigating linker scripts and the functionality needed to support them in lld. I have attached my findings about the usage of ldscripts. My findings have been collected from: - Reading all the GNU ld manual sections about linker scripts. - Looking at the GNU ld and gold source code. - Digging through a couple embedded programming tutorials. - Reading through all of the linker scripts in the Linux kernel tree. - Other random sourc...

16396:055d98aa2dd0 almost works but not quite. LDFLAGS_DIRECT means we end up with: gld -melf_i386 -nostdlib -N -Ttext 0x100000 -o hvmloader.tmp hvmloader.o mp_tables.o util.o smbios.o 32bitbios_support.o acpi/acpi.a Specifying a linker script and asking for -nostdlib is obviously contradictory. Removing $(LDFLAGS_DIRECT) fixes the problem. regards john

MEMORY and most aspects of SECTIONS are effectively syntax sugar and the rest of LLD doesn't need to even be aware of it; the ldscript language processor will desugar it. The same is true of many other linker script constructs that I didn't mention. The goal of the write-up was to describe the primitive functionality that will be needed at the boundary between the language processor and the rest of LLD (although admittedly som...

Hi vedant, The program didn't pass the checking "OF->getArch() != Triple(Arch).getArch()" loadBinaryFormat in CoverageMappingReader.cpp and returned an error. It's because "OF->getArch()" returned null and "Triple(Arch).getArch()" returned XXXX(name of my arch). The returned value of " OF->getArch()" is decided by "

New error was “Failed to load coverage: No coverage data found” since the compiler cannot get NamesSection(at loadBinaryFormat in CoverageMappingReader.cpp). I thought it was my ldscript problem because I put __llvm_prf_names, __llvm_prf_cnts, __llvm_prf_data and __llvm_prf_vnds inside .rodata section.

From: Sylvain Gault <sylvain.gault at gmail.com> These patches basically remove unused linker scripts and port a change that was made to an unused script. Those are to be applied on top of the gcc 5 bug fixes as they would conflict otherwise.

Hi, We have a whole bunch of readers(we would have some more too), and was thinking if we should have a vector of Readers, and have a function isMyFormat in each of them. Any reader that knows to handle, goes ahead and parses the file. On a side note, we currently use .objtxt as an figure out if the file is a YAML file or not. I have added FIXME's in the code, if we could some kind of

From: Sylvain Gault <sylvain.gault at gmail.com> These few patches contain a few improvement about the Makefiles for EFI. Mainly, to rebuild the files when needed, and only when needed. The three shell scripts efi/{check,build,clean}-gnu-efi.sh disappeared and are now integrated as makefile recipes. You'll notice an argument ARFLAGS=rvU to the recursive make calls to gnu-efi. This is

The PNaCl project has implemented various IR simplification passes that simplify LLVM IR by lowering complex features to simpler features. We'd like to upstream some of these IR passes to LLVM. We'd like to explore if this acceptable, and if so, how we should go about doing this. The immediate reason is that Emscripten is reusing PNaCl's IR passes for its new "fastcomp"
