[Bug binutils/27865] Unsupported name-unmangling for C++20 modules?
https://sourceware.org/bugzilla/show_bug.cgi?id=27865 --- Comment #5 from Nick Clifton --- Hi Guys, It sounds like we may be jumping the gun a bit if we push for an update to libiberty before this mangling scheme is fully defined... Maybe it would be best to hold off for a bit ? Cheers Nick -- You are receiving this mail because: You are on the CC list for the bug.

Remove initial_length_size var and instead calculate end_cu. Use end_cu to limit data reads.

[Bug gas/27878] [z80-unknown-elf]: ld (hl), <16 bit immediate> should fail assembly
https://sourceware.org/bugzilla/show_bug.cgi?id=27878 --- Comment #1 from Pete Moore --- Interestingly, the assembler will fail if the out-of-range value comes from a label rather than an explicitly specified constant in the assembly source code: ``` $ cat test.asm .org 0x1232 ; value chosen intentionally so that label == 0x1234 ld (hl), label label: $ z80-unknown-elf-as -o test.o test.asm && z80-unknown-elf-objdump -d test.o test.asm: Assembler messages: test.asm:2: Error: value of 4660 too large for field of 1 byte at 4659 ``` This is the output I was also expecting for `ld (hl), 0x1234`. Note, if the `.org 0x1232` is removed, label fits in 8 bits, and assembly succeeds, as expected. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug gas/27888] New: fix link of gas with zlib by libtool 2.4.6
https://sourceware.org/bugzilla/show_bug.cgi?id=27888
Bug ID: 27888
Summary: fix link of gas with zlib by libtool 2.4.6
Product: binutils
Version: 2.35.2
Status: NEW
Severity: minor
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: nicolas at debian dot org
Target Milestone: ---
Created attachment 13460
--> https://sourceware.org/bugzilla/attachment.cgi?id=13460&action=edit
patch always passing -lz and only removing -L with-system-lib
When running autoreconf -f -i with libtool 2.4.6,
then configuring with --with-system-zlib,
the linker fails to find the deflate symbol for gas.
For the record, -f works without -i.
The attached patch copies the solution used by {bfd,binutils}/Makefile.am.
