Schema parameters
by J. David Bryan 27 Jul '06

27 Jul '06

Running gpc-20060325 on i486-pc-mingw32, this program: program params (output); procedure p1 (s1 : string; s2 : string); begin writeln ('in p1') end; procedure p2 (s1, s2 : string); begin writeln ('in p2') end; begin p1 ('l', 'hello'); p2 ('l', 'hello') end. ...produces this output when compiled with --gnu-pascal: in p1 in p2 ...but this output when compiled with --extended-pascal: in p1 params: actual schema discriminants do not match (error #308 at 401426) Is this correct? -- Dave

64 bit
by Silvio a Beccara 25 Jul '06

25 Jul '06

Dear friends, if I run GPC on a 64 bit machine (an AMD Athlon 64 X2 ), it is supposed to produce 64-bit code, is it right? But what are then the sizes of the various integer types available in GPC? If I let this code program sizes; begin writeln ('# size of integer is = ', sizeof (integer) ); writeln ('# size of medint is = ', sizeof (medint) ); writeln ('# size of longint is = ', sizeof (longint) ); end. print them out, I get these results: # size of integer is = 8 # size of medint is = 8 # size of longint is = 8 is that right? Shouldn't it be like 4,8,16?

Change in packing between compiler versions
by Martin Liddle 20 Jul '06

20 Jul '06

I am continuing to struggle with some code that compiles and runs as intended using gpc-20020502 based on gcc 2.95.2 that I am now trying to get it running with gpc-20060325 based on gcc-3.4.4. It appears the packing of records has changed. The following test program produces different answers with the different compilers Program mltest06; Const MaxName=49; MaxClas=40; MaxChel=120; Type TCompr=Packed Record Name:String(Maxname); Class:1..Maxclas; Awel:Set of 1..MaxChel; Rlate,Rtime:Integer; RetirementControl:Integer; PerformanceIndex:Integer; END; Var Compr:TCompr; Begin Writeln('Size of Compr =',Sizeof(Compr)); Writeln('Size of Compr.Name =',BitSizeof(Compr.Name)); Writeln('Size of Compr.Class =',BitSizeof(Compr.Class)); Writeln('Size of Compr.Awel =',BitSizeof(Compr.awel)); Writeln('Size of Compr.Rlate =',BitSizeof(Compr.Rlate)); Writeln('Size of Compr.Rtime =',BitSizeof(Compr.Rtime)); Writeln('Size of Compr.RetirementControl=',BitSizeof(Compr.RetirementControl)); Writeln('Size of Compr.PerformanceIndex =',BitSizeof(Compr.PerformanceIndex)); End. 20020502 20060325 Size of Compr =91 96 Size of Compr.Name =464 480 Size of Compr.Class =6 6 Size of Compr.Awel =128 128 Size of Compr.Rlate =32 32 Size of Compr.Rtime =32 32 Size of Compr.RetirementControl=32 32 Size of Compr.PerformanceIndex =32 32 Is there a command line option for gpc to obtain the previous behaviour with the newer version? -- Martin Liddle, Tynemouth Computer Services, 3 Kentmere Way, Staveley, Chesterfield, Derbyshire, S43 3TW.

Correct way to access Errno
by Martin Liddle 20 Jul '06

20 Jul '06

We have some code that compiles and runs as intended using gpc-20020502 based on gcc 2.95.2. I am now trying to get it running with gpc-20060325 based on gcc-3.4.4. As a demonstration the program Program Test_err; Var errno:integer; external name 'errno'; Begin Writeln(@Error number is ',Errno); End; Compiles but fails to link with 20060325 : "/usr/bin/ld: errno: TLS definition in /lib/libc.so.6 section .tbss mismatches non-TLS reference in /tmp/ccae8f7a.o" The same program runs correctly with 20020522 when external name is replaced by the older syntax asmname. A bit of googling suggests this is a common problem and not limited to gpc but I can't find how I am now supposed to access errno. Any suggestions? -- Martin Liddle, Tynemouth Computer Services, 3 Kentmere Way, Staveley, Chesterfield, Derbyshire, S43 3TW. Web site: <http://www.tynecomp.co.uk>.

Can Assert report the file name and line number?
by Bastiaan Veelo 19 Jul '06

19 Jul '06

Hi, I have a lot of assertions. If one of them fails, GPC only reports something like "assertion failed (error #306 at 40dd45)". How can I find out the exact assertion that failed? Thanks, Bastiaan.

Hi! I would like to know if I use mkdiff to create diff-file to gcc-4.1.1 can gpc work. If can, how I use mkdiff? I've been tried to do it, but I've been get many errors(no such file or directory). What can I do? Thanks, Bruno
