As xterm modifies the 50 exported termcap, this would cause those modifications to be ignored. 51 kcah 52 53 hack wi-at-big-endian-bus 54 cdate 15 Mar 2002 55 who martin 56 file dev/ic/wireg.h 57 descr Add an option to access the underlying bus in big endian byte order 58 to work around deficiencies in bus_space_{read,write}_* macros. 59 Those don't allow the implementation of a proper pcmcia bus space 60 tag. 61 kcah 62 63 hack specific knowledge of colours in curses code 64 cdate Sun Apr 6 11:05:24 BST 2003 65 who jdc 66 file lib/libcurses/color.c : r1.24 67 descr 68 Swap red/blue and yellow/cyan colours for COLOR_OTHER. 69 Fix is to enhance libtermcap to understand terminfo-style % sequences. 70 See also: 71 http://mail-index.NetBSD.org/tech-userlevel/2003/04/06/0000.html 72 kcah 73 74 hack Compensation for differing types of LINUX_USRSTACK and USRSTACK 75 cdate 21 Aug 2003 76 who he 77 file sys/miscfs/procfs/procfs_linux.c : 1.14 78 descr 79 Not all ports have LINUX_USRSTACK and/or USRSTACK defined as 80 literals/constants, but refer to variables of a type which is 81 not "unsigned long", causing compilation of procfs_linux.c to 82 fail with "makes integer from pointer without a cast". This 83 is observed on e.g. the sun3 port. Ideally the "types" for 84 symbols should be consistent across all ports. 85 kcah 86 87 hack gcc-strict-aliasing 88 cdate 6 August 2004 89 who junyoung 90 pr 26516 91 file src/usr.sbin/racoon/racoon/Makefile : 1.21 92 descr 93 GCC issues a warning "dereferencing type-punned pointer will break 94 strict-aliasing rules" when compiling 95 crypto/dist/kame/racoon/crypto/openssl.c with -O[23s]. Note that this 96 is due to use of type casting in a non-standard way in the code and 97 not a compiler bug. Once a new release of KAME with a proper fix 98 applied is imported this should be backed out. 99 kcah 100 101 hack gcc4 wrong uninitialized variable 102 mdate 10 May 2006 103 who mrg 104 file bin/ksh/eval.c : 1.6 105 file bin/sh/histedit.c : 1.39 106 file bin/sh/parser.c : 1.60 107 file crypto/dist/heimdal/kdc/524.c : 1.10 108 file crypto/dist/ssh/sftp.c : 1.20 109 file crypto/dist/ssh/ssh-keysign.c : 1.11 110 file dist/ipf/lib/hostname.c : 1.2 111 file dist/ipf/tools/ipmon.c : 1.8 112 file dist/ntp/ntpd/ntp_request.c : 1.4 113 file dist/ntp/ntpd/refclock_shm.c : 1.4 114 file dist/ntp/sntp/timing.c : 1.3 115 file dist/pppd/pppstats/pppstats.c : 1.3 116 file dist/smbfs/lib/smb/rap.c : 1.6 117 file dist/tcpdump/print-zephyr.c : 1.5 118 file distrib/utils/sysinst/aout2elf.c : 1.12 119 file gnu/libexec/uucp/uucico/uucico.c : 1.6 120 file lib/libc/citrus/citrus_csmapper.c : 1.6 121 file lib/libc/citrus/citrus_pivot_factory.c : 1.5 122 file lib/libc/inet/inet_cidr_ntop.c : 1.3 123 file lib/libc/inet/inet_ntop.c : 1.3 124 file lib/libc/stdio/vfwprintf.c : 1.8 125 file libexec/ld.elf_so/arch/m68k/mdreloc.c : 1.20 126 file libexec/ld.elf_so/arch/powerpc/ppc_reloc.c : 1.40 127 file libexec/ld.elf_so/arch/sh3/mdreloc.c : 1.22 128 file libexec/ld.elf_so/arch/sparc/mdreloc.c : 1.39 129 file libexec/ld.elf_so/arch/sparc64/mdreloc.c : 1.39 130 file libexec/ld.elf_so/arch/vax/mdreloc.c : 1.21 131 file libexec/ld.elf_so/arch/x86_64/mdreloc.c : 1.27 132 file sbin/fsck_ext2fs/dir.c : 1.19 133 file sbin/routed/rtquery/rtquery.c : 1.18 134 file sys/arch/amd64/amd64/pmap.c : 1.26 135 file sys/arch/i386/pci/piixpcib.c : 1.4 136 file sys/arch/m68k/m68k/pmap_motorola.c : 1.4 137 file sys/crypto/cast128/cast128.c : 1.9 138 file sys/ddb/db_command.c : 1.86 139 file sys/dev/cardbus/cardbus_map.c : 1.21 140 file sys/dev/fss.c : 1.25 141 file sys/dev/ic/igsfb.c : 1.39 142 file sys/dev/ic/mb86950.c : 1.5 143 file sys/dev/ic/midway.c : 1.71 144 file sys/dev/kttcp.c : 1.18 145 file sys/dev/rasops/rasops_bitops.h : 1.9 146 file sys/dev/pci/cmpci.c : 1.31 147 file sys/dev/pci/machfb.c : 1.45 148 file sys/dev/usb/ohci.c : 1.174 149 file sys/dev/usb/uhci.c : 1.196 150 file sys/dev/rasops/rasops_bitops.h : 1.9 151 file sys/dist/ipf/netinet/ip_nat.c : 1.10 152 file sys/dist/ipf/netinet/ip_rpcb_pxy.c : 1.8 153 file sys/dist/pf/net/pf.c : 1.22 154 file sys/fs/udf/udf_vnops.c : 1.4 155 file sys/kern/kern_sig.c : 1.219 156 file sys/kern/tty.c : 1.181 157 file sys/net/bpf.c : 1.116 158 file sys/net/zlib.c : 1.26 159 file sys/netccitt/if_x25subr.c : 1.37 160 file sys/netinet/in.c : 1.107 161 file sys/netsmb/smb_smb.c : 1.27 162 file sys/netsmb/smb_trantcp.c : 1.22 163 file sys/nfs/nfs_serv.c : 1.108 164 file sys/nfs/nfs_socket.c : 1.129 165 file sys/nfs/nfs_syscalls.c : 1.91 166 file sys/ufs/lfs/lfs_vfsops.c : 1.207 [also (char *)] 167 file usr.bin/ftp/ftp.c : 1.140 168 file usr.bin/find/function.c : 1.54 169 file usr.bin/mail/tty.c : 1.20 170 file usr.bin/msgc/msg_sys.def : 1.33-1.34 171 file usr.bin/nl/nl.c : 1.7 172 file usr.bin/systat/keyboard.c : 1.23 173 file usr.bin/usbhidctl/usbhid.c : 1.29 174 file usr.bin/vi/cl/cl_read.c : 1.5 175 file usr.bin/vi/ex/ex_cscope.c : 1.12 176 file usr.bin/vi/ex/ex_tag.c : 1.19 177 file usr.bin/vi/vi/v_txt.c : 1.15 178 file usr.sbin/altq/altqstat/qdisc_rio.c : 1.4 179 file usr.sbin/cron/do_command.c : 1.19 180 file usr.sbin/timed/timed/slave.c : 1.15 181 descr 182 GCC 4.1 gets many uninitialised variable warnings wrong. We should 183 really audit all the old hacks like this when older compilers are 184 removed from the tree, as many are probably no longer required. 185 The problem is that it does not recognize initialization via function 186 call pointer.

The check to fix this in 515 rev 1.107 only checks the first psection of the ELF 516 executable, which may not be loadable. A more correct 517 fix is to check the first loadable psection instead of 518 just the first psection. 519 kcah 520 521 hack mips-duplicate-ras-end-label 522 cdate Sat Sep 2 23:29:42 2006 523 who martin 524 file src/regress/sys/kern/ras/ras3/Makefile : 1.3 525 descr 526 Add -fno-reorder-blocks to CFLAGS to avoid duplicate 527 labels by duplicated __asm output from RAS_END() 528 macro. 529 kcah 530 531 hack mips-mcount-assembler-warning 532 cdate Tue Jul 29 14:16:52 UTC 2008 533 who lukem 534 file src/lib/libc/gmon/Makefile.inc : 1.8 535 descr 536 Workaround for PR port-mips/39192. 537 common/lib/libc/gmon/mcount.c generates a (fatal) 538 assembler warning on MIPS: 539 Warning: No .cprestore pseudo-op used in PIC code 540 Add COPTS.count.c+=-Wa,--no-warn to avoid -Wa,--fatal-warnings 541 kcah 542 543 port i386 544 545 hack use volatile intermediate variable to enforce rounding 546 cdate Tue Aug 1 22:15:55 MEST 2006 547 who drochner 548 file src/lib/libm/src/lrintf.c : 1.4 549 file src/lib/libm/src/s_rintf.c : 1.8 550 descr 551 gcc-4 does subsequent operations on "float" values within 552 the i387 FPU without rounding the intermediate results 553 kcah 554
