Hi there, When I compile my code with -fdata-sections and -ffunction-sections, I still see some unused string in my shared library (Android). Actually, the strings appear together inside a .rodata.str1.1 section instead of getting their own section. It seems that the C-string literal are considered differently than other constant and the -fdata-sections is not respected in

Hi, I'm in the process of migrating from clang5 to clang10. Unfortunately clang10 introduced a negative performance impact. The cause is an increase of PLT entries from this patch (first released in clang7): https://bugs.llvm.org/show_bug.cgi?id=36370 https://reviews.llvm.org/D43383 If I revert that clang patch locally, the additional PLT entries and the performance impact disappear. This

Hello All, I was trying to add Microblaze target to LLVM backend. I was able to generate object file with relocations. and debug symbols. When I try to link this object file with microblaze GCC linker I am getting below errors and debug symbols are missing in it. mb-objdump: DWARF error: found dwarf version '15877', this reader only handles version 2, 3, 4 and 5 information

Hello. I have been trying to check, how llvm works on Solaris recently. First I have tested lli, whitch seems to execute the bytecode generated on Linux without any problems. However, llc has failed to generate valid SPARC assembler code even on the helloworld example. Here is the generated code: sakharov at trillian:~$ cat ./test.s .text .align 16 .globl main

Were those errors from trying to dump the linked executable, and not errors that were produced by the linker itself? Yes, as mentioned earlier I was able to generate final executable but it

Hi, We’d like to propose an extension to both the map file and the print-gc/icf-sections output. This extension would be to report the pieces of .eh_frame and SHF_MERGE sections in these files somehow. Since all (or at least the majority) of the contents of these sections in the output come from inputs, it would be beneficial in trying to associate the output contents with where they came from,

> You used -noinhibit-exec to ignore the diagnostic, which is usually a bad thing. I certainly agree with that. The point I was trying to make in my original email is that, specifically for kernel objects, this diagnostic is incorrect. R_X86_64_PC32 can be used safely against the symbol foo in that specific context, and should be possible without ignoring diagnostics. I wondered if there

In compiling perlbench in SPEC2006 today, I get the following asm code: .4byte ($debug_loc2280) .4byte 1 .4byte PerlIO_fd_refcnt $set1406 = ($.bss_end)-PerlIO_fd_refcnt .4byte ($set1406) .4byte PerlIO_perlio $set1407 = ($.data_end)-PerlIO_perlio .4byte ($set1407) .4byte ($func_begin0) $set1408 = ($.text_end)-($func_begin0) .4byte

With the MIPS compiler, when we have static constants, in the .s file we get something like: .type $.str33, at object # @.str33 .section .rodata.str1.1,"aMS", at progbits,1 $.str33: .asciz "//" .size $.str33, 3 Currently when we create direct object code we are referencing the symbol as an offset in .rodata and not directly using

I was looking into the AsmPrinter and the method EmitSectionOffset which contains this code: -------------------------------------------------------------------------------- // If the section in question will end up with an address of 0 anyway, we can // just emit an absolute reference to save a relocation. if (Section.isBaseAddressKnownZero()) { OutStreamer.EmitSymbolValue(Label, 4,

Hi everyone, *1.* I had a file called server.cpp that i can run using: g++ -o server server.cpp -lrpc -ldl -lpthread *2.* Converted the file into LLVM IR, modified it and saved to file using the WriteBitcodeToFile function. The name of resulting file is "output". *3.* Used llc command for generation of "output.o" file as: llc -filetype=obj output *4.* Used gcc command to

It seems that showing eh_frame section pieces in the map file is useful, but I wonder what would be a concrete use case of the feature. Do you mind if you ask you to describe your plan if you have a use case in mind?

Hi James, Thanks for reply. When I looked in to the generated debug dump from the object file I found that DW_AT_name is always (indirect string, offset: 0x0): clang version 8.0.1, instead of variable names. Below is a sample output of the debug dump. Compilation Unit @ offset 0x0: Length: 0x6a (32-bit) Version: 4 Abbrev Offset: 0x0 Pointer Size: 4

Hello, Running some examples to see how LLVM work, I found that some pseudo operations are unknown. Details are shown below. This is the command sequence that I am using: > llvm-gcc -O3 -emit-llvm hello.c -c -o hello.bc > llc -march=arm hello.bc -o hello-arm.s > arm-linux-gcc hello-arm.s -o hello-arm ************************ hello.s:6: Error: Unknown pseudo-op: `.eabi_attribute'

Not totally sure about this. Perhaps we should make ./configure look for the right asmrun library? Or make it user-configurable? Rich.
