Assembly error while building GHC 7.7

I get the same error with my:

$ uname -a
Linux tn24 3.2.0-39-generic #62-Ubuntu SMP Wed Feb 27 22:05:17 UTC 2013 i686 i686 i386 GNU/Linux

I have tried running the failing assmbly by hand with -E:

$ '/usr/bin/gcc' '-fno-stack-protector' '-DTABLES_NEXT_TO_CODE' '-Ilibraries/base/dist-install/build' '-Ilibraries/base/dist-install/build' '-Ilibraries/base/dist-install/build/autogen' '-Ilibraries/base/include' '-x' 'assembler-with-cpp' -E '-c' '/home/tn/tn/GHCGitRepository/ghc/delete/ghc1351_0/ghc1351_3.s'

The resulting output contains:

 call 1 .get_pc_thunk.bx

This is in agreement with http://sourceware.org/bugzilla/show_bug.cgi?id=411 that describes problems caused by the name __i686 unexpectedly being defined as a macro by gcc.

As a temporary fix, adding

SRC_HC_OPTS     += -opta-U__i686

to mk/build.mk enables the build to proceed.

Thanks for the link, Thorkil. Could you test whether instead changing all 4 instances of __i686 in compiler/nativeGen/PIC.hs to __x86 works, please?

Could you test whether instead changing all 4 instances of __i686 in compiler/nativeGen/PIC.hs to __x86 works, please?

I have tried that (where, by the way, ___i686 in compiler/nativeGen/PIC.hs is with three leading underscores) but, unfortunately, it didn't help. And, in fact, the curious fact seems to be that the code that gcc, the asssembler, complains about has been generated by gcc, the C compiler.

In an attempt to clarify, I ran the failing compile like this:

$ "inplace/bin/ghc-stage1" -hisuf hi -osuf  o -hcsuf hc -static  -H32m -O    -package-name base-4.7.0.0 -hide-all-packages -i -ilibraries/base/. -ilibraries/base/dist-install/build -ilibraries/base/dist-install/build/autogen -Ilibraries/base/dist-install/build -Ilibraries/base/dist-install/build/autogen -Ilibraries/base/include   -optP-DOPTIMISE_INTEGER_GCD_LCM -optP-include -optPlibraries/base/dist-install/build/autogen/cabal_macros.h -package ghc-prim-0.3.1.0 -package integer-gmp-0.5.1.0 -package rts-1.0 -package-name base -XHaskell98 -XCPP -O2  -no-user-package-db -rtsopts      -odir libraries/base/dist-install/build -hidir libraries/base/dist-install/build -stubdir libraries/base/dist-install/build -split-objs -dynamic-too -c libraries/base/./System/Posix/Internals.hs -o libraries/base/dist-install/build/System/Posix/Internals.o -dyno libraries/base/dist-install/build/System/Posix/Internals.dyn_o -v -tmpdir T7799-tmpdir -keep-tmp-files > T7799-tmpdir/ghc_T7799.out 2>&1

I will attach T7799-tmpdir.tar.gz, the contents of the resulting T7799-tmpdir directory. For convenience, this contains much which is similar to the original report.

T7799-tmpdir/ghc_T7799.out contains

ghc26404_1.c: Assembler messages:

ghc26404_1.c:138:0:
     Error: junk `.get_pc_thunk.bx' after expression
...

Although the assembler error report mentions the file ghc26404_1.c, it can be seen that the complaints actually concerns the contents of ghc26404_2.s. Confirming this

$ head -138 T7799-tmpdir/ghc26404_0/ghc26404_2.s | tail -1
	call	__i686.get_pc_thunk.bx
$

where the complaint is caused by the replacement shown earlier of "__i686" by "1 ".

Hmm, thanks Thorkil; very curious.

I can't reproduce it here, but the above patch should fix it.
