This gcc5 package can be installed alongside Slackware's gcc-11
packages. These version 11 compilers can sometimes be quite a bit
more strict about what they accept as valid code. As a consequence,
you will regularly run into compilation issues with software. Not just
the software made with the scripts on slackbuilds.org, but also some
of the software in the Slackware core distribution requires patches in
order to get them to compile.
Still having the gcc version 5 compilers can sometimes be a lifesaver.
Particulars of the gcc5 package:
- The gcc5 binaries were given a suffix '-5' to make them stand apart
from Slackware's default compilers.
- The gcc5 package only contains the C, C++ and Java compilers.
- One all-encompassing package is built by the SlackBuild script.
- Profile scripts are added to /etc/profile.d/. You can 'source'
the profile script to prefer the gcc-5 compilers over gcc-7.
- On 64bit Slackware, the gcc5.SlackBuild will detect an existing gcc
multilib compiler and will then build a multilib capable gcc5.
If you run pure 64bit Slackware, then a pure 64bit gcc5 package is
built.
How to use these gcc5 compilers instead of Slackware's default ones?
Simple:
In your console or terminal, you 'source' the provided profile script,
like this (a c-shell compatible script is available as well):
source /etc/profile.d/gcc5.sh
The command 'source' is equivalent to the dot command ' . '.
The profile script will (re-)define the common variables that are
used by make and other programs to determine which binary to run as
the compiler:
export CC=gcc-5
export CPP=cpp-5
export CXX=g++-5
export AR=gcc-ar-5
export NM=gcc-nm-5
export RANLIB=gcc-ranlib-5
Nothing else needs to be done after sourcing the profile script.
All you do next is run your compile job as usual in that same console.
Your program will be compiled with the binaries provided by the gcc5
package.
** WARNING: The temporary build location used by the script
** (defaulting here to /tmp/SBo) should *NOT* be a directory path a
** non-root user could create later...

# Some notes, Fri May 16 12:31:32 PDT 2003:
#
# Why i486 and not i386? Because the shared C++ libraries in gcc-3.2.x will
# require 486 opcodes even when a 386 target is used (so we already weren't
# compatible with the i386 for Slackware 9.0, didn't notice, and nobody
# complained :-). gcc-3.3 fixes this issue and allows you to build a 386
# compiler, but the fix is done in a way that produces binaries that are not
# compatible with gcc-3.2.x compiled binaries. To retain compatibility with
# Slackware 9.0, we'll have to use i486 (or better) as the compiler target
# for gcc-3.3.
#
# It's time to say goodbye to i386 support in Slackware. I've surveyed 386
# usage online, and the most common thing I see people say when someone asks
# about running Linux on a 386 is to "run Slackware", but then they also
# usually go on to say "be sure to get an OLD version, like 4.0, before glibc,
# because it'll be more efficient." Now, if that's the general advice, then
# I see no reason to continue 386 support in the latest Slackware (and indeed
# it's no longer easily possible).
# Some more notes, Mon Aug 3 19:49:51 UTC 2015:
#
# Changing to -march=i586 for 32-bit x86 as several things (Mesa being one of
# them) no longer work if constrained to -march=i486. We're not going to use
# -march=i686 since the only additional opcode is CMOV, which is actually less
# efficient on modern CPUs running in 32-bit mode than the alternate i586
# instructions. No need to throw i586 CPUs under the bus (yet).

Subject: [PATCH 1/9] i386: Move struct ix86_frame to machine_function
Make ix86_frame available to i386 code generation. This is needed to
backport the patch set of -mindirect-branch= to mitigate variant #2 of
the speculative execution vulnerabilities on x86 processors identified
by CVE-2017-5715, aka Spectre.
Backport from mainline
* config/i386/i386.c (ix86_frame): Moved to ...
* config/i386/i386.h (ix86_frame): Here.
(machine_function): Add frame.
* config/i386/i386.c (ix86_compute_frame_layout): Repace the
frame argument with &cfun->machine->frame.
(ix86_can_use_return_insn_p): Don't pass &frame to
ix86_compute_frame_layout. Copy frame from cfun->machine->frame.
(ix86_can_eliminate): Likewise.
(ix86_expand_prologue): Likewise.
(ix86_expand_epilogue): Likewise.
(ix86_expand_split_stack_prologue): Likewise.

Subject: [PATCH 3/9] i386: More use reference of struct ix86_frame to avoid copy
When there is no need to make a copy of ix86_frame, we can use reference
of struct ix86_frame to avoid copy.
Backport from mainline
* config/i386/i386.c (ix86_expand_prologue): Use reference of
struct ix86_frame.
(ix86_expand_epilogue): Likewise.

Subject: [PATCH 5/9] x86: Add -mindirect-branch= (documentation)
Add -mindirect-branch= option to convert indirect call and jump to call
and return thunks. The default is 'keep', which keeps indirect call and
jump unmodified. 'thunk' converts indirect call and jump to call and
return thunk. 'thunk-inline' converts indirect call and jump to inlined
call and return thunk. 'thunk-extern' converts indirect call and jump to
external call and return thunk provided in a separate object file. You
can control this behavior for a specific function by using the function
attribute indirect_branch.
2 kinds of thunks are geneated. Memory thunk where the function address
is at the top of the stack:
__x86_indirect_thunk:
call L2
L1:
pause
lfence
jmp L1
L2:
lea 8(%rsp), %rsp|lea 4(%esp), %esp
ret
Indirect jmp via memory, "jmp mem", is converted to
push memory
jmp __x86_indirect_thunk
Indirect call via memory, "call mem", is converted to
jmp L2
L1:
push [mem]
jmp __x86_indirect_thunk
L2:
call L1
Register thunk where the function address is in a register, reg:
__x86_indirect_thunk_reg:
call L2
L1:
pause
lfence
jmp L1
L2:
movq %reg, (%rsp)|movl %reg, (%esp)
ret
where reg is one of (r|e)ax, (r|e)dx, (r|e)cx, (r|e)bx, (r|e)si, (r|e)di,
(r|e)bp, r8, r9, r10, r11, r12, r13, r14 and r15.
Indirect jmp via register, "jmp reg", is converted to
jmp __x86_indirect_thunk_reg
Indirect call via register, "call reg", is converted to
call __x86_indirect_thunk_reg

[UBUNTU NOTES: Updated for gcc-5.4 to include defines for
FIRST_INT_REG, LAST_INT_REG, and LEGACY_INT_REGNO_P as defined in
https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=222269.
Dropped indirect-thunk-5.c, indirect-thunk-6.c,
indirect-thunk-bnd-3.c, indirect-thunk-bnd-4.c,
indirect-thunk-extern-5.c, indirect-thunk-extern-6.c,
indirect-thunk-inline-5.c, and indirect-thunk-inline-6.c tests due
to gcc 5.4 and earlier not supporting the -fno-plt option.

Subject: [PATCH 6/9] x86: Add -mfunction-return=
Add -mfunction-return= option to convert function return to call and
return thunks. The default is 'keep', which keeps function return
unmodified. 'thunk' converts function return to call and return thunk.
'thunk-inline' converts function return to inlined call and return thunk.
'thunk-extern' converts function return to external call and return
thunk provided in a separate object file. You can control this behavior
for a specific function by using the function attribute function_return.
Function return thunk is the same as memory thunk for -mindirect-branch=
where the return address is at the top of the stack:
__x86_return_thunk:
call L2
L1:
pause
lfence
jmp L1
L2:
lea 8(%rsp), %rsp|lea 4(%esp), %esp
ret
and function return becomes
jmp __x86_return_thunk
-mindirect-branch= tests are updated with -mfunction-return=keep to
avoid false test failures when -mfunction-return=thunk is added to

i386: Don't use ASM_OUTPUT_DEF for TARGET_MACHO
ASM_OUTPUT_DEF isn't defined for TARGET_MACHO. Use ASM_OUTPUT_LABEL to
generate the __x86_return_thunk label, instead of the set directive.
Update testcase to remove the __x86_return_thunk label check. Since
-fno-pic is ignored on Darwin, update testcases to sscan or "push"
only on Linux.

Subject: [PATCH 7/9] x86: Add -mindirect-branch-register (documentation)
Add -mindirect-branch-register to force indirect branch via register.
This is implemented by disabling patterns of indirect branch via memory,
similar to TARGET_X32.
-mindirect-branch= and -mfunction-return= tests are updated with
-mno-indirect-branch-register to avoid false test failures when
-mindirect-branch-register is added to RUNTESTFLAGS for "make check".

Subject: [PATCH 7/9] x86: Add -mindirect-branch-register
Add -mindirect-branch-register to force indirect branch via register.
This is implemented by disabling patterns of indirect branch via memory,
similar to TARGET_X32.
-mindirect-branch= and -mfunction-return= tests are updated with
-mno-indirect-branch-register to avoid false test failures when
-mindirect-branch-register is added to RUNTESTFLAGS for "make check".

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description. Line
# up the first '|' above the ':' following the base package name, and the '|' on
# the right side marks the last column you can put a character in. You must make
# exactly 11 lines for the formatting to be correct. It's also customary to
# leave one space after the ':'.
