In order to extend the termcap string over 1023 bytes, a ZZ entry was

|
introduced to point to a memory location containing the full entry.
|
|
|
|
|
Without this hack, xterm will export a termcap containing the ZZ
|
|
|
|
|
entry, which will then be ignored by libterm. As xterm modifies the
|
|
|
|
|
exported termcap, this would cause those modifications to be ignored.

Not all ports have LINUX_USRSTACK and/or USRSTACK defined as

|
|
literals/constants, but refer to variables of a type which is
|
|
|
|
|
not "unsigned long", causing compilation of procfs_linux.c to

|
|
|
|
fail with "makes integer from pointer without a cast". This
|
|
|
|
|
is observed on e.g. the sun3 port. Ideally the "types" for
|
|
|
|
|
symbols should be consistent across all ports.

GCC 4.1 gets many uninitialised variable warnings wrong. We should
|
|
|
|
|
really audit all the old hacks like this when older compilers are
|
|
|
|
|
removed from the tree, as many are probably no longer required.
|
2006-05-15 08:55:13 +04:00

The problem is that it does not recognize initialization via function
|
|
|
|
|
call pointer. I.e.
|
|
|
|
|
int p;
|
|
|
|
|
foo(&p);
|
|
|
|
|
does not mark p as initialized.

Our cabs and cabsf have a different argument format on some architectures

|
|
and for that we have created in libm/compat_cabs{,f}.c. The standard
|
|
|
|
|
versions in libc are __c99_cabs{,f,l} and there are __RENAME()'s in
|
|
|
|
|
<complex.h>. G++ uses __builtin_cabs{,f,l} to implement those and they
|
|
|
|
|
translate by default to cabs{,f,l} which gets defined to cabs{,f} (the
|
|
|
|
|
wrong function) and an undefined cabsl. I've changed <complex> to use
|
|
|
|
|
the __c99_cabs{,f,l} directly. Using the __builtin_cabs{,f,l} in gcc is
|
|
|
|
|
still broken.

Something is wrong with GCC 4.5.3 and the savefpstate IPI.
|
|
|
|
|
Post newlock2 there was a bug where a lock was reduced from
|
|
|
|
|
IPL_SCHED to IPL_VM (?) and occasionally savefpstate IPI
|
|
|
|
|
would crash due to NULL IPI. This was fixed by re-using the
|
|
|
|
|
right IPL value. However, GCC 4.5.3 build kernels have the
|
|
|
|
|
same problems. For now, the hack is re-instated.

With COMPAT_16 or previous enabled (which enables
|
|
|
|
|
ELF_INTERP_NON_RELOCATABLE) a recent ld.elf_so will
|
|
|
|
|
load and run at address 0. The check to fix this in
|
|
|
|
|
rev 1.107 only checks the first psection of the ELF
|
|
|
|
|
executable, which may not be loadable. A more correct
|
|
|
|
|
fix is to check the first loadable psection instead of
|
|
|
|
|
just the first psection.

exist in a MKGCC=no world. To allow rpcgen to work out-of-the-box,

The in-tree gcc 9/gcc 10 crashes with an internal
|
|
|
|
|
invalid opcode exception when using any kind of
|
|
|
|
|
optimization on lex.c in usr.bin/xlint/lint . This
|
|
|
|
|
was introduced apparently unintendedly in gcc when
|
|
|
|
|
addressing a different issue. Rather than disabling
|
|
|
|
|
optimization for lex.c, instead revert the change to
|
|
|
|
|
gcc. The bug report upstream has been updated to
|
|
|
|
|
reflect the exact breakage.
